Creating deterministic zips now

Did not know that zips by default weren't deterministic. Because of this, if 2 people used the script to make the mod and tried to join each other's game, it would fail as despite their mods being identical, they would have completely different hashes. Luckily I found Bryce Boe's deterministic_zip script, which solves the issue.
