This is basically prep work for customisable sort orders. The room sort parameters are detached from the room sort model as multiple components will need to access the values. The sorting is then generified.
Some defunct sorting parameters are also removed.
Make sure that the new rules for counting notifications for muted, mention and low priority rooms is applied consistently to the room list, space drawer and the task manager notification badge
implements #644
Update the UX to refer to structure direct chats as friends. The direct chats are pulled into their own tab in the space drawer.
The `UserDetailDialog` is also updated to check whether a direct chat already exists and if not ask to invite as friend.
Unread count is deprecated and notification count should be used in all cases. As such remove unreadCount and use notification count in all places it was being used.

BUG: 466515
Rework the filtering of state events in the timeline and for lastevent. This is now consistent everywhere and includes the following:
- The timeline settings are obeyed everywhere
- A new setting is added to filter all state events
- Last event obeys the timeline setting in all cases
- The roomlist will show a state event as the latest event if it's visible in the timeline
- Names are no longer hyperlinked in eventToString if plaintext is selected.
