Create Test Media App

This application is intended to help test the Car/Media app by making it
easy to send it media items and playback states. Those media items are
bundled within the assets of the TestMediaApp, as very readable json files.

Quick overview:
 - loader package interprets the json files
 - prefs package implements the app's preferences
     (account type, root node, reply delay)
 - TmaBrowser implements the MediaBrowserService. It send replies
     based on the content of the prefs and the json files
 - TmaLibrary caches the interpreted files
 - TmaPlayer simulates all media interactions (without playing any sound)
 - TmaMediaItem represents the media items of the test app
 - TmaMediaEvent represents playback events to send to the media session
