We no longer have tinting support, so remove it. We still need the `Tinter` to exist though as it's used in quite a few places (though does nothing). Similarly, we have to keep the `roomColor` setting due to it being used in a few places - another PR can take away the tinter support properly.
The room tile context menu and top left menu are artifacts of the old room list.
The end to end tests weren't failing before as the code path is unused, however it seems worthwhile to keep it as we will eventually need it.
This takes out the old user and room settings, replacing the paths with the new dialog editions. The labs setting has been removed in order to support this change.
In addition to removing the old components outright, some older components which were only used by the settings pages have been removed. The exception is the ColorSettings component as it has a high chance of sticking around in the future.
Styles that were shared by the settings components have been broken out to dedicated sections, making it easier to remove the old styles entirely.
Some stability testing of the app has been performed to ensure the app still works, however given the scope of this change there is a possibility of some broken functionality.
