Connect audio settings button

Rework to connect the audio settings button on the media pages
to the appropriate settings page, and have the back button go
back to the expected previous page.  To enable this, the global
AppState provider was reworked to track the previous page and add
explicit update and back member functions.

Bug-AGL: SPEC-5030
