Fast Heretic v2 addon

By The Drake Raider. Just threw together a mod I wanted to make, that made Heretic faster paced. So far I've changed every enemy and weapon found in the first episode. Uploading it because I figured other people might like it. Now the full second episode has new monster behaviour, with some new weapon changes. I have two weapons left to do (Pheonix Rod, Firemace), and two enemies (Ophidian, D'Sparil.)
