Add a tab bar to the room drawer which includes a new media tab in addition to the room information tab. This mr completes the architecture for adding others easily later e.g. message highlights or threads.
To put this together I had to make sure things like the menus and the maximize delegate were available to both the room drawer and page so there is some rework there to put it all together.

Add handling for new default push rules added in 1.7 also add a generic unknown handling for if any others are added in the future so they don't appear in keywords
Previously, some functions that conceptually belong to the connection needed to be in the Controller, since we didn't have a place to put them.
This fixes that by extending the Connection class in a similar way as we extend the Room class.
Merge the functionality of CollapseStateProxyModel into MessageFilterModel there is no need for a whole separate model the filters can be combined trivialy.
Push the room drawer as a page rather than a drawer when on mobile or the window is thin.
This also lays some foundations for having multiple different pages in the drawer by separating the room information into it's own component which could be switched out to show other things like highlights or media.
Add a timer to lockout the scroll trigger for marking messages as read in the first second after changing room. This is because the scrollview can't differentiate between mouse scrolling and the multiple changes in scrollview that happen as the room is changed over.
