this commit introduces autocomplete feature to the muc-list group chat dialog,
previously there was only an input field which displayed hardcoded servers.
inside `parseMessageForMUCCommands`.
If the function doesn't find any core MUC commands, it calls
`parseMessageForCommands` which will trigger the hook.
I think it's appropriate to give built-in commands preference above
commands by 3rd party plugins and this also solves the issue of the hook
being triggered twice (once in `parseMessageForMUCCommands` and
then again in `parseMessageForCommands`).
Instead of on the views/components.
We still have `close` methods on the components, but they are just
event handlers and not external API methods to be called by other code.
Instead `close` should be called on the model.
- Move `showModeratorToolsModal` method from view to utils
- Move `getNicknameRequiredTemplate` method from view to utils
- Move common `close` code to base class
Had to make various other changes due to incompatibilities.
- Use the new `lit` package instead of `lit-html` or `lit-element`
- Drop `haunted` since it breaks the rules by specifying `type: module`
but then doesn't import with file extensions
- Use Sass Dart instead of node-sass (fixes#2445)
- Upgrade Karma
- Move top-level functinos to utils files
- Get rid of unused/obsolete overrides
- Only import components there where they're used
- Bump version in package.json
