## TLDR
* Improve performance: lazy creating the tippy instances.
* Transparently support all "tooltip" elements, no need to call
`initTooltip` again and again.
* Fix a temporary tooltip re-entrance bug, which causes showing temp
content forever.
* Upgrade vue3-calendar-heatmap to 2.0.2 with lazy tippy init
(initHeatmap time decreases from 100ms to 50ms)
## Details
### The performance
Creating a lot of tippy tooltip instances is expensive. This PR doesn't
create all tippy tooltip instances, instead, it only adds "mouseover"
event listener to necessary elements, and then switches to the tippy
tooltip
### The general approach for all tooltips
Before, dynamically generated tooltips need to be called with
`initTooltip`.
After, use MutationObserver to:
* Attach the event listeners to newly created tooltip elements, work for
Vue (easier than before)
* Catch changed attributes and update the tooltip content (better than
before)
It does help a lot, eg:
1a4efa0ee9/web_src/js/components/PullRequestMergeForm.vue (L33-L36)
### Temporary tooltip re-entrance bug
To reproduce, on try.gitea.io, click the "copy clone url" quickly, then
the tooltip will be "Copied!" forever.
After this PR, with the help of `attachTippyTooltip`, the tooltip
content could be reset to the default correctly.
### Other changes
* `data-tooltip-content` is preferred from now on, the old
`data-content` may cause conflicts with other modules.
* `data-placement` was only used for tooltip, so it's renamed to
`data-tooltip-placement`, and removed from `createTippy`.

Here made the change inside the `contextpopup.js` because this is where
the popup component is created and tippy configuration is given.

### The CustomEvent prefix
There was already `ce-quick-submit`, the `ce-` prefix seems better than
`us-`. Rename the only `us-` prefixed `us-load-context-popup` to `ce-`
prefixed.
### Styles and Attributes in Go HTML Template
https://github.com/go-gitea/gitea/pull/21855#issuecomment-1429643073
Suggest to stick to `class="c1 {{if $var}}c2{{end}}"`
The readability and maintainability should be applied to the code which
is read by developers, but not for the generated outputs.
The template code is the code for developers, while the generated HTML
are only for browsers.
The `class="c1 {{if $var}}c2{{end}}"` style is clearer for developers
and more intuitive, and the generated HTML also makes browsers happy (a
few spaces do not affect anything)
Think about a more complex case:
* `class="{{if $active}}active{{end}} menu item {{if $show}}show{{end}}
{{if $warn}}warn{{end}}"`
* --vs--
* `class="{{if $active}}active {{end}}menu item{{if $show}}
show{{end}}{{if $warn}} warn{{end}}"`
The first style make it clearer to see each CSS class name with its
`{{if}}` block.

- Replace all default exports with named exports, except for Vue SFCs
- Remove names from Vue SFCs, they are automatically inferred from the
filename
- Misc whitespace-related tweaks
By appending the tooltips to `document.body`, we can avoid any stacking context issues caused by surrounding element's CSS.
This uses [tippy.js](https://github.com/atomiks/tippyjs) instead of Fomantic popups. We should aim to replace all Fomantic popups with this eventually and then get rid of the Fomantic `popup` module completely.
Introduce 'make svg' which calls a node script that compiles svg files
to `public/img/svg`. These files are vendored to not create a dependency
on Node for the backend build.
On the frontend side, configure webpack using `raw-loader` so SVGs can
be imported as string.
Also moved our existing SVGs to web_src/svg for consistency.

* 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.
