Subject: * Updates LSL2CS converter * All objects are not touchable by default
 now * When a script listens for one of the touch events in the state, an
 object becomes touchable. * All LSL scripts report which events they consume
 now ** This uses semi-complicated Regex to discover the events, stick them in
 a dictionary, and then write a method call into each script state's
 state_entry() event. ** Tedd may figure out a better way to do this in the
 future.  For now, this works for LSL.
