Add gamemode_query_status and teach gamemoded '-s'

Browse Source 
This allows the client to query the daemon about the status of gamemode.

	Returns the following:
		 0 if gamemode is inactive
		 1 if gamemode is active
		 2 if gamemode is active and this client is registered
		-1 if the query failed

	Passing -s to gamemoded will simply query and print the current status.

	Allows for more comprehensive testing when using 'gamemoded -r' as well as more reactionary program behaviour
