Subject: [PATCH] android: Add intents for service start and stop

org.musicpd.action.StartService
org.musicpd.action.StopService

You can test these actions like:
adb shell am broadcast -a org.musicpd.action.StartService org.musicpd

Calling these from an app like tasker should allow for automation
