issue-keyword class is being incorrectly stripped off spans (#16163)
Bluemonday sanitizer regexp rules are not additive, so the addition of the icons,
emojis and chroma syntax policy has led to this being stripped.

Remove NULs byte arrays passed to PostProcess (#14587)
PostProcess is supposed to be parsing and handling HTML
fragments, but on fuzzing it appears that there is a weird
issue with NUL elements that could cause a memory address
error in downstream libraries.

The simplest solution is to strip out the weird NULs - they
should not be there in any case and would be stripped out
anyway.

Update emoji regex (#11584)
When matching emoji, use a regex built from the data we have instead of something generic using unicode ranges. A generic regex can't tell the difference between two separate emoji next to each other or one emoji that is built out of two separate emoji next to each other.

This means that emoji that are next to each other without space in between will be now accurately spanned individually with proper title etc...

Allow different HardBreaks settings for documents and comments (#11515)

Support unicode emojis and remove emojify.js (#11032)
* 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.
