I moved the code for the tray icon to separate files and also separeted gui logic from daemon logic a bit more.
Further more I fixed the behavior of the Icon tray.

When the next sync type is changed to a non-default one the default checkbox gets unchecked and after a sync the default sync is selected again.

Last but not least, the dbus interfaces are now only created when necessary.
So when KPilot is not started, the dbus interfaces will not be created.
I'm not sure if it was possible before but you now can sync with only the daemon started.
