Add -clientid command line option that adapts the ID for SingleApp

Browse Source 
When the app is started with "-client -clientid <id>" it only reuses an
instance that was also started with "-clientid <id>". It adds the ID as
a postfix to the normal application ID that is used for the
QtSingleApplication.
