4.59.0

* Fixed: Appearance of the page when viewing a Watch Party.
* Fixed: During the initial load, some CSS blocks could be incorrectly injected into the page due to a race condition.
* Fixed: The sample embed in Chat > Appearance >> Rich Content not appearing correctly.
* API Added: New event class `FFZWaitableEvent`, a subclass of `FFZEvent` providing a framework for asynchronous event handlers.
* API Added: `site.channel:update-bar` event, fired whenever the channel info bar is updated.
* API Fixed: `chat.removeTokenizer()`, `chat.removeLinkProvider()`, and `chat.removeRichProvider()` failing to fully remove their respective items.
* API Removed: The `emitAsync` method has been removed from modules. Nothing was using it, and it was problematic due to the concurrent access protection on events. Instead, `FFZWaitableEvent` should be used if asynchronous waiting is necessary.
