Accept library function names as vars in simple_expr in globals

Browse source 
This may cause more trouble than it's worth, but it's how LSL behaves and one of our objectives is to document the darker corners of LSL. Mono chokes at the RAIL postprocessing stage, not in compilation proper. LSO chokes at runtime for string, key and list, and works fine for the other types.
