Make sure that KDE Connect daemon is running
move KDE Connect detection to KDEConnectManager
better daemon detection and spawning
will detect whether daemon is running and spawn it if it is'nt
Merge branch 'wip/detect_running_daemon'

Indicator now should:
- detect if org.kde.kdeconnect is running
- spawn /usr/lib/kde3/libexec/kdeconnectd if file is exist
- retry to detect after spawning
- show an error message dialog if both fail
