Spider-Man PS1 Beta: Playable Sewer Stages

SolidSnake11 has fixed this Beta Version when it comes to several levels and scripts, and so I've decided to fix both Sewer Stages entirely since they were not playable at all. I didn't even had to remove Venom for both levels.
I'll upload this fixed version on Dropbox if I get the respective permission of SolidSnake11.
