Closes#38
Add a nav drawer link to a new favorites page which shows favorited
Movies, TV Shows, and Episodes.
Also adds a button to movies & tv shows to set/unset favorite status.
Click the version in settings 3 times to open this new debug page which
displays internal information such as settings, server info, app info,
and database info. It will also show recently logcat messages.
Adds support for playing different versions of a media item.
Additionally, you can pick the audio or subtitle tracks for the chosen
version.
The file with the highest resolution is the default, but you can switch
versions or tracks in the "More" menu.
These choices are persisted across playbacks, just as in #26.
Remembers changes in playback tracks across playbacks. So, if you change
the audio track, quit the app, and return to the same id, the app will
play the audio track previously chosen.
Additionally, this PR fixes a UI inconsistency when there are multiple
versions of a item. Previously sometimes the audio/subtitle tracks for
wrong version would be shown during playback.
Fixes#21
Might also address #18
Fixes an issue with logging using username/password due to network
access on wrong thread exceptions.
Also adds better handling when deleting users or servers, especially if
it's the current one.
Adds a tab to the TV Show & Movie screens which displays the genres in
that library as a grid.
You can select the genre to see the items in that library for the genre.
This PR also adds backend changes for further filtering to implement
#13.
