From b6b1402368b8f33c825af095bec210829ad33cd3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] * Changed Game::_variables to public since the GPL
 interpreter needs to use it and made it int instead of uint16 * Implemented
 variable accessing by the math evaluator * Fixed bug from previous commit
 (should have used && when checking for ending instructions, not ||)
