Mobile Pages

Currently the page experienc on mobile is suboptimal as back gestures do not work and the startup behaviour is not ideal.

This reworks it so that pages are now pushed as a layer on mobile and at startup only a saved space is restored. It is also setup so that on mobile you'll never see a blank room page (like when you select friends or home).
