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.

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.
