* 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.
