Ugly as Sin v4.1.3c

This is a maintenance release, since people are still playing on HD 4.1.3c and getting script errors when trying to use the old verison of Ugly as Sin.

No changelog, sorry. Mostly under-the-hood tweaks. Download the "Source Code (zip)" below and run it like a .pk3, no renaming or unzipping necessary.

Note this is not a current release, nor is it intended to be used with HD's "bleeding edge master". It's merely to maintain version compatibility for those playing on stable releases.
