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
