Bill Currie db8cf68ef3 [gamecode] Pass registered data pointer to builtins
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.

Closes #26
