First make sure that the global setting is tied into the room setting, previously it was a bit of a patchwork that worked more by luck than judgement. The two levels of global and room level are properly tied together in a hierarchy.
Add a message in the room when global notifcations re turned off. This has caused confusion in the past when people don't realise there are 2 levels.
The problem lies in how media URLs work, in this case it the old
NeoChatRoom::avatarMediaId could pass a mxc url *or* a path that can
be put into root.connection.makeMediaUrl. So normal rooms with avatars
loaded, but never friends because room members gave the mxc URL.
Instead, change everything to use avatarMediaUrl which corrects this
issue by always passing a mxc URL to QML. This also removes the need to
call makeMediaUrl.
Fixes#675
Fix the InlineMessages for the room upgrades in RoomSettings, they should show even if we aren't currently in the room. Resolve resource can join the predecessor/sucessor if required.
