More fixes to get it to compile for me on Mac 10.9. Mostly just newline additions, but some of the unused variables were causing errors, so I wrapped them in #ifndef __APPLE__ calls, since I didn't know if they were going to be used in the future.

Also had to undefine TOLUA_TEMPLATE_BIND a couple of times.
