New design for the navigation bars

This version introduce a new design for the navigation bars, both on desktop and mobile. Nothing big but it should gives some more feedback when navigating between the different Movim zones.

Avatars refresh fixes

Several bugs around the avatars refresh were also fixed. #Movim now properly check if the #avatar is not already in cache before trying to refresh it again.

The avatar refresh queries are also now spread in time using a super simple scheduler. This helps lowering the network (and I/O) load when logging in.

Some avatars placeholders were also not displayed in some chatrooms, this version fix this small issue.

Chatroom administration panel

The previous version introduced a refactor that broke the #chatroom administration panel access. Its now fixed ☺️

join.movim.eu fixes

Not directly related with this release, but join.movim.eu was also updated to support the newest Movim versions. If you are a server admin, do not hesitate to register your instance there ☺️

That's all folks!
