Improve server in use check when using live TV/DVR

Browse source 
Monitor live TV and DVR sessions in addition to regular streams when
doing a in use check for the server. Paused streams are not considered
to be "in use" so if all streams that are playing are currently paused,
the updated will continue regardless.

Closes #177
