Commits unrelated to the upcoming large PR.
MPDroid: Add 'service' module, rearrange code.

Setup a service module, this commit should have no impact on the running code.
MPDroidService: Unbinding from the service causes the callee to die.

A wonderful side effect of binding is the service dies if the connection is
lost. This is actually useful in our case, so use it to it's fullest.
MPDroid: Add a helper method for choosing no cover art image.
MPDroidService: Remove current track updating from updatePlayingInfo.
MPDroidService: Remove seek time from updatePlayingInfo.
MPDroidService: Remove album cover updating from updatePlayingInfo.
MPDroidService: Move RemoteControlClient/MediaButtonReceiver to it's own class.
RemoteControlClientHandler: Store by RCC playstate.
MPDApplication: Move settings/warnings shown into the outer class.
MPDApplication: Dynamically check service status.

Setting & unsetting server status is not fullproof. Servers can crash, and
generally, go out of sync easily. This is approach is fullproof and clean.

This patch also removes the ApplicationState inner class as it is now unused.
RemoteControlReceiver: If notification closed during stream, stop stream.

Short log is confusing here; actually, if the notification close button is hit
on the notification, while streaming service is open, shut off the streaming
service as well. This can only occur while not playing, as the button won't
be visible, otherwise.
StreamingService: WOUND_UP -> BEGIN_BUFFERING.
MPDroidService: Setup listener for shared settings.
MPDroidService: Move notification code to it's own class.
MPDroidService: Move album cover updating to it's own class.
