-KEY BUTTONS
-
-Continuous button event tracking is complicated by the fact that two different
-input sources (say, mouse button 1 and the control key) can both press the
-same button, but the button should only be released when both of the
-pressing key have been released.
-
-When a key event issues a button command (+forward, +attack, etc), it appends
-its key number as a parameter to the command so it can be matched up with
-the release.
-
-state bit 0 is the current state of the key
-state bit 1 is edge triggered on the up to down transition
-state bit 2 is edge triggered on the down to up transition
