Site update | Notifications/UI

Hello! A technical update:
- The "Guild" tab now takes you straight to your guild's chat instead of the search.
- The "Guild alliance" tab is no longer a separate tab of the section, it is now a subsection inside the chats (visible both in the global chat and in the guild one)
- Fixed a bug where temporary rooms disappeared or their members were not shown.
- Notifications can now be turned off for a whole section or for one particular chat, either for good or for a while (keep in mind that notifications only ever carry pings anyway)

UI:
- Chat categories are told apart much more clearly, and they can be collapsed
- Changed how many emoji fit in a row (before that they were too small, and the unique ones were not sorted)
- Added a beaver emoji
- Menu icons stand out on phones

And a pleasant observation for iOS owners:
- If you use the site through Safari (not through the home screen shortcut, but simply opened in the browser, that part matters) the microphone does not drop when you minimise it.
We made no changes in that direction, we are preparing an app, but the observation is worth your attention: the users we asked follow this instruction and have no trouble.
