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.

* add request review feature in pull request
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.
