[maemo-developers] Check if application is run

[From: Michael Stepanov]

Well if I understand clearly I have to define dbus services for SDL
application and for its maemo wrapper (it's already done for the wrapper).
And then listen in the wrapper events sent from the SDL application. Catch
'crash' event or similar and run it again. Right?
