Currently you can see a list of commit history for wiki pages but aren't able to view the commit diff itself. This adds the feature to view an individual commit to a wiki repo.

* Switch code editor to Monaco
This switches out CodeMirror for Monaco which is based on the same code
base as VS code and should work pretty similar to it.
It does add a few async chunks, totalling around 10MB to our build. It
currently supports around 65 languages and in the default configuration,
each language would emit one ugly [number].js chunk, so I opted to
combine them all into a single file for now.
CodeMirror is still being used under the hood by SimpleMDE so it can not
be removed yet.

* routers: make /compare route available to unauthenticated users
Remove some bits of the compare interface if the user isn't signed in.
Notably, they don't need to see the "New Pull Request" button box nor the
hidden form that would fail to submit due to the POST request continuing to
require proper privileges.
Follow-up commits will improve the UI a bit around this, removing some
"Pull Request" verbiage in favor of "Compare."
* ui: home: show "compare" button for unauthenticated users
This change requires pulling in the BaseRepo unconditionally and
recording if the pull request is in-fact not allowed
(.PullRequestCtx.Allowed). If the user isn't allowed to create a pull
request, either because this isn't a fork or same-fork branch PRs aren't
allowed, then we'll name the button "Compare" instead of "Pull Request."
* ui: branch list: use the new Compare language when available
When viewing the branch listing as an unauthenticated user, you'll get
"Pull Request" buttons. use the new "Compare" verbiage instead, which
matches GitHub behavior when you can't issue a pull request from the
branches.

* Support unicode emojis and remove emojify.js
This PR replaces all use of emojify.js and adds unicode emoji support to various areas of gitea.
This works in a few ways:
First it adds emoji parsing support into gitea itself. This allows us to
* Render emojis from valid alias (😄)
* Detect unicode emojis and let us put them in their own class with proper aria-labels and styling
* Easily allow for custom "emoji"
* Support all emoji rendering and features without javascript
* Uses plain unicode and lets the system render in appropriate emoji font
* Doesn't leave us relying on external sources for updates/fixes/features
That same list of emoji is also used to create a json file which replaces the part of emojify.js that populates the emoji search tribute. This file is about 35KB with GZIP turned on and I've set it to load after the page renders to not hinder page load time (and this removes loading emojify.js also)
For custom "emoji" it uses a pretty simple scheme of just looking for /emojis/img/name.png where name is something a user has put in the "allowed reactions" setting we already have. The gitea reaction that was previously hard coded into a forked copy of emojify.js is included and works as a custom reaction under this method.
The emoji data sourced here is from https://github.com/github/gemoji which is the gem library Github uses for their emoji rendering (and a data source for other sites). So we should be able to easily render any emoji and :alias: that Github can, removing any errors from migrated content. They also update it as well, so we can sync when there are new unicode emoji lists released.
I've included a slimmed down and slightly modified forked copy of https://github.com/knq/emoji to make up our own emoji module. The code is pretty straight forward and again allows us to have a lot of flexibility in what happens.
I had seen a few comments about performance in some of the other threads if we render this ourselves, but there doesn't seem to be any issue here. In a test it can parse, convert, and render 1,000 emojis inside of a large markdown table in about 100ms on my laptop (which is many more emojis than will ever be in any normal issue). This also prevents any flickering and other weirdness from using javascript to render some things while using go for others.
Not included here are image fall back URLS. I don't really think they are necessary for anything new being written in 2020. However, managing the emoji ourselves would allow us to add these as a feature later on if it seems necessary.

add a way to notify specific reviewers to review like github , by add or delet a special type
review . The acton is is similar to Assign , so many code reuse the function and items of
Assignee, but the meaning and result is different.
The Permission style is is similar to github, that only writer can add a review request from Reviewers,
but the poster can recall and remove a review request after a reviwer has revied even if he don't have
Write Premission. only manager , the poster and reviewer of a request review can remove it.
The reviewers can be requested to review contain all readers for private repo , for public, contain
all writers and watchers.
The offical Review Request will block merge if Reject can block it.
an other change: add ui otify for Assignees.

* Add organization wide labels
Implement organization wide labels similar to organization wide
webhooks. This lets you create individual labels for organizations that can be used

labels effectively.

* Don't sort repos by date in IssuesSearch API
After much debugging I've found a strange issue where in some cases MySQL will return a different result than other enigines if a query is sorted by a null collumn. For example with our integration test data where we don't set updated_unix in repository fixtures:
SELECT `id`, `owner_id`, `owner_name`, `lower_name`, `name`, `description`, `website`, `original_service_type`, `original_url`, `default_branch`, `num_watches`, `num_stars`, `num_forks`, `num_issues`, `num_closed_issues`, `num_pulls`, `num_closed_pulls`, `num_milestones`, `num_closed_milestones`, `is_private`, `is_empty`, `is_archived`, `is_mirror`, `status`, `is_fork`, `fork_id`, `is_template`, `template_id`, `size`, `is_fsck_enabled`, `close_issues_via_commit_in_any_branch`, `topics`, `avatar`, `created_unix`, `updated_unix` FROM `repository` ORDER BY updated_unix DESC LIMIT 15 OFFSET 45
Returns different results for MySQL than other engines. However, the similar query:
SELECT `id`, `owner_id`, `owner_name`, `lower_name`, `name`, `description`, `website`, `original_service_type`, `original_url`, `default_branch`, `num_watches`, `num_stars`, `num_forks`, `num_issues`, `num_closed_issues`, `num_pulls`, `num_closed_pulls`, `num_milestones`, `num_closed_milestones`, `is_private`, `is_empty`, `is_archived`, `is_mirror`, `status`, `is_fork`, `fork_id`, `is_template`, `template_id`, `size`, `is_fsck_enabled`, `close_issues_via_commit_in_any_branch`, `topics`, `avatar`, `created_unix`, `updated_unix` FROM `repository` ORDER BY updated_unix DESC LIMIT 15 OFFSET 30
Returns the same results.
This causes integration tests to fail on MySQL in certain cases but would never show up in a real installation. Since this API call always returns issues based on the optionally provided repo_priority_id or the issueID itself, there is no change to results by changing the repo sorting method used to get ids earlier in the function.
