* Added JSON datafiles for TV shows and music videos
* Implemented instrumentations tests for MoviesActivity, MusicActivity,
TVShowActivity, and AddonsActivity.
* Moved RestoreSearchQueryViewPagerTest to music package as it uses
the MusicActivity
* Moved RestoreSearchQueryListFragmentTest to movies packages as it
uses the MoviesActivity
* Added scripts to get JSON data for music videos, addons, and TV shows
* Added sequence diagram for BaseMediaActivity to clarify new setup
* Refactored BaseMediaActivity to comply with diagram
* Refactored SyncMusicVideos and SyncTVShows so we can use the same code
for adding test data as we use for adding real data.
* Removed unused StringBuffer and synchronize block in MockTcpServer
This allows us to test activities and fragments that require JSON RPC calls.
The ApplicationTest for JSON method and notification calls is mainly added
as example and for testing the MockTcpServer and friends.
