* Update to version 4 of webpack.
* For that matter, update *every dependency* to the latest available version.
* Remove the babel build target for Edge, as it doesn't seem to be necessary with webpack 4 and tenser.
* Add support for optional chaining and nullish coalescing via Babel transformations.
* Update the clips domain version to work better. Or at all, really.
* Remove unused code from i18n.
* Remove the last `<style>` from vue component files. They don't work that way now anyways.

* Fix a bug with the menu button in browsers that don't understand `:scope` within `querySelector()`.
This adds a new module called switchboard that abuses the root React Router instance to forcibly load a chunk, letting us grab `require()` quickly rather than waiting potentially forever for another chunk to be loaded due to user action, etc.
* Add extensible actions system.
* Add extensive UI for configuring the actions system.
* Add setting to disable channel hosting.
* Fix the stupid Rooms thing popping up every time you open a channel.
* Fix how we grab chat types from React.
* Refactor how we handle incoming chat messages.
* Add a hook for outgoing chat messages.
* Fix emoji appearing squished with baseline emote alignment.
* Display arrows on balloons.
* Fix an issue generating emoji URLs.
* Do not use the default values for settings with merge strategies if profiles have those settings, just empty.
* Display a message in the chat settings menu if we tried opening FFZ's settings and failed.
* Wait a bit for webpack's loader if it's not immediately there for some reason.
* Probably other stuff.
* Not mod cards. Yet.
