Keyboard hook fixes, added targetRefresh command

Keyboard hook class now only listens for Hot Keys and not a all keys in
a global keyboard hook.  This should fix the reliability of the keyboard
hook.
Added a new command targetRefresh which will allow you to refresh the
XML on a specified window and not the entire desktop.  This will help if
you want to speed up the synthuse script by not continuously doing full
refreshes of the xml.
