- Update all JS dependencies to latest versions
- Add new lint rules, enable es2022 eslint parser features
- Disable github/no-then, I feel the rule was too restricting
* Add new JS linter rules
Adds a few useful rules from eslint-plugin-github. Notable changes:
- Forbid dataset usage, its camel-casing behaviour makes it hard to
grep for attributes.
- Forbid .then() and .catch(), we should generally prefer await for new
code. For rare cases where they are useful, a eslint-disable-line
directive can be set.
- Add docs js to linting
* also enable github/array-foreach
* small tweak

Use async clipboard api [1] over this dependency, saving around 10kB

This adds editorconfig-checker [1] to lint the template files so they
conform the editorconfig files. I fixed all current identation issues
using the fix mode of eclint [2] and some manual corrections.
We can extend this linting to other files later, for now I'd like this

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.

This saves around 3 MB binary size by not including useless fomantic
files in the build. Also, this allows us to move jQuery into the main
bundle as well which eliminates a few HTTP requests.
Also included are webpack config changes:
- split less and css loaders to speed up compliation
- enable css sourcemaps
- switch css minfier plugin to cssnano-webpack-plugin which works better
for sourcemaps than the previous plugin

* Add automatic JS license generation
Removed librejs file and replaced it with a plaintext file that is built

This removes the jQuery plugin as well as the associated config options.
Native input[type=date] does not require a language attribute as it is
localized by default, except for the placeholder attribute for which I
currently piggy-back the repo.issues.due_date_form localization option.
Implementation should pretty much match GH. Of note is that Safari does
not provide a UI for this input type, but I don't think providing one is
neccessary and GH did not bother either.

Instead of statically hardcoding every frontend asset, this uses a

this new implementation doesn't.

* 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.

This should eliminate page freezes when loading big files/diff.
`highlightBlock` is needed to preserve existing nodes when highlighting
and for that, highlight.js needs access to the DOM API so I added a DOM
implementation to make it work, which adds around 300kB to the output
file size of the lazy-loaded `highlight.js`.

- Added 'lint', 'lint-frontend', 'lint-backend' targets
- Added 'lint-frontend', 'lint-backend' ci steps and restructure the
'compliance' pipeline to have a clear separation between frontend and
backend and use parallelism where possible. Also, the main build
pipelines now depend on 'compliance' so they will skip if it fails.
- Added dependencies on ci steps so they skip when 'compliance' fails
- Moved JS linters to devDependencies
- Removed deprecated 'js' and 'css' targets
- move all JS build dependencies to 'dependencies'
- update all JS dependencies
Reason for this is that npm will only install 'dependencies' when under
the effect of NODE_ENV=production which may be present on some build
systems.
Linters currently need to be depdendencies because we run linting as
part of the build step, but I plan to move them to a separate 'lint'
target which means they can move to devDependencies then.

This changes the CSS output of webpack to output to the public/css
directory instead of inling CSS in JS. This enables CSS minification and
autoprefixer based on browserslist which would otherwise not be

- public/css/swagger.css
- public/css/gitgraph.css

Currently, this needs to be its own chunk because fomantic depends
on jQuery being present. The next step is to move fomantic to webpack
too after which we can combine the index,fomantic and jquery files into
one.
jquery-migrate is still neccessary because our ancient version of Dropzone
seems to break without it. I imagine it can be removed after a Dropzone
upgrade.

Created a second webpack output file for swagger-ui which is loaded on
the /api/swagger route. One notable difference is the absence of the
swagger favicon that was previously used which is now the gitea icon. I
see no easy way to restore that favicon, so I decided to not keep it.
- moved gitgraph.js to web_src and made it importable and es6-compatible
- created new webpack chunk for gitgraph
- enabled CSS loader in webpack
- enabled async/await syntax via regenerator-runtime
- added script to ensure webpack chunks are loaded correctly
- disable terser's comment extraction to prevent .LICENCE files
gitgraph.js has many issues:
1. it is incompatible with ES6 because of strict-mode violations
1. it does not export anything
1. it's css has weird styles like for `body`
1. it is not available on npm
I fixed points 1-3 in our version so it's now loadable in webpack. We should eventually consider alternatives.
