MPDroid: Intellij/SDK plugin updates.
MPDroid: Travis update.
NowPlayingSmallFragment: Move the UpdateTrackInfo listener to onResume()/onPause().
NowPlayingFragment: Do extra connection checking in forceStatusUpdate().
PhoneStateReceiver: Make local audible aware, clean streaming service.

Refactor the phone state receiver local audible aware, which allows removal of
all telephony service handling from the streaming service. This also makes use
of MPDControl.

This patch also allows the phone settings pause & resume to be individually
set, as resume might be prefered by the user, but not pause on call. Since
pause will occur on local audible (and will override preference) the user
will have he choice to resume.

Some minor changes
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. I
fully expect to replace this functionality as soon as I can figure out a more
robust method of accomplishing this.

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.
