* 'openahelp' command

* Add AHelp into escape menu

* Add a way to ahelp a player from the kick window

 "Changed the adminhelpsound to some creative commons sound I pinched. Until somebody can get a better one. I'm sick of MAAAAAAAAOOOOOOW."

 The sound had been reversed and the volume altered.

* Actually play the bwoink sound on receiving an ahelp that you didn't send
