Mantis#2183. Thank you kindly, Ewe Loon for a patch that addresses:

after using llTakeControls my sim receives about 200 messages per second, 
l of which get queued , this could be because there is no lag as the viewer 
and sim are on the same computer. The patch I have included checks to see if 
the "Changed" param is 0 then searches the EventQueue for Control messages 
being sent to the same localid, if it finds a message already in the Queue 
and Changed==0 then the new message is only notifing you the key is being held, 
since there is already a message the new one isnt needed so it isnt added 
to the queue.
