Altered turboEvent to allow the while held workaround to work.

Altered turboEvent to allow the while held workaround that people use
in Xpadder to work in AntiMicro. I have ran into the while held issue
a few times while playing Mass Effect 2 so I figured that implementing
the workaround described at
http://xpadder.com/forum4/viewtopic.php?f=88&t=1282
would be useful.
