Propagate exceptions as higher as possible

so that the error is shown to the user and hopefully he can understand it.

• DaemonCommander now throws exceptions
• Running/Stopped statuses are no longer gray
• Failure statuses are better reported (not just Unknown)
• Menu enabling is handled by a single function

I'm actually not sure showing raw errors to the user make sense most of the time ;) It's just internal technical details, which ideally we'd turn into some more understandable higher level message. Quite hard though

LGTM, Status are correctly reflected now, and code became much cleaner then before 🎉 Thanks!!
