Now that emojify.js has been removed, get rid of all instances of has-emoji class that was only used for that. Support for rendering shortcodes should remain in all of these places so it should still work the same.

* 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.

* Fix task-list checkbox styling
The pandoc renderer will append the class "task-list" to the ul element
wrapping a li with one or more check-boxes. This allows us to select for
them, removing their list-style-type property. However, goldmark and the
gfm spec doesn't specify the "task-list" class name, so we can't use
that to fix the issue there.

* Don't manually replace whitespace during render
For historical reasons Gitea manually alters the urlPrefix and replaces
a whitespace with a +. This Works for URLs, but we're also passing
urlPrefix to git calls and adding the + is breaking the tree path.
Goldmark will automatically convert a white space to the proper %20, so
we should leave the string as is which lets us pass it to git unmodified
and then let Goldmark fix it.
Also fixed separate bug in URLJoin I noticed while testing where it will
silently discard sections of a path that have # in them (possibly
others). We should just escape it first.

* Move to goldmark
Markdown rendering moved from blackfriday to the goldmark.
Multiple subtle changes required to the goldmark extensions to keep
current rendering and defaults.
Can go further with goldmark linkify and have this work within markdown
rendering making the link processor unnecessary.
Need to think about how to go about allowing extensions - at present it
seems that these would be hard to do without recompilation.

* Support custom sanitization policy
Allowing the gitea administrator to configure sanitization policy allows
them to couple external renders and custom templates to support more
markup. In particular, the `pandoc` renderer allows generating KaTeX
annotations, wrapping them in `<span>` elements with class `math` and
either `inline` or `display` (depending on whether or not inline or
block mode was requested).
This iteration gives the administrator whitelisting powers; carefully
crafted regexes will thus let through only the desired attributes
necessary to support their custom markup.

* Check commit message hashes before making links
Previously, when formatting commit messages, anything
that looked like SHA1 hashes was turned into a link
using regex. This meant that certain phrases or numbers
such as `777777` or `deadbeef` could be recognized as a commit
even if the repository has no commit with those hashes.
This change will make it so that anything that looks
like a SHA1 hash using regex will then also be checked
to ensure that there is a commit in the repository
with that hash before making a link.

Since #6273 was merged, we now have access to proper context metas
always. Update SHA generated links to use these instead of urlPrefix.
Update tests as well.
Fixes #4536.
* Improve issue autolinks
Update autolinks to match what github does here:
Issue in same repo: #1
Issue in different repo: org/repo#1
Fixes #6264
* Use setting.AppURL when parsing URL
Using setting.AppURL here is a more reliable way of parsing the current
URL and what other functions in this file seem to use.
* Make ComposeMetas always return a valid context
* Add per repository markdown renderers for better context
* Update for use of context metas
Now that we include the user and repo name inside context metas, update
various code and tests for this new logic
* Use stricter boundaries for auto-link detection
Currently autolinks use \W for boundary detection which creates many
situations of inserting links into places they don't belong (paths,
URLs, UUIDs, etc...)
This fixes that by replacing \W and only allowing these matches to touch
an open paren or bracket (matching what seems to be Github behavior) in
addition to whitespace and start of line. Similar for ending boundary as
well.
Fixes #6149
(and probably others)
* Update test
Replace incorrect test with a value that is a valid username, based on:
"Username should contain only alphanumeric, dash ('-'), underscore ('_')
and dot ('.') characters."
* Also allow for period at the end
Matching Github behavior
* Fix email regex to work properly with specificed boundaries
Create a specific capture group for email address and then use
FindStringSubmatchIndex to allow for non-matching patterns as
boundaries.
* Add Tests
Add tests for new behavior -- including tests for email addresses which
were absent before.
This improves the SHA1 link detection to not pick up extraneous
non-whitespace characters at the end of the URL. The '.' is a special
case handled in code itself because of missing regexp lookahead
support.
