Removed MPC library from source (now in its own repository, see readme for details). Completely decoupled MPC library from the app. Converted most functions to be synchronous which decreases UI thread lag and means updates to volume/playing/shuffle only happen when the server registers them. Made database update trainsactional which has drastically improved performance and reliability.
