- Made Kinsie's Test Map changes toggleable (off by default)
- Corrected physics of various projectiles
- Replaced textures of health items to something better looking
- Biosludge now only has a hitbox when stuck to surfaces, to be
more consistent with vanilla behavior
- Some code cleanup
Switch ambientglow+brightmap shader to actually use brightmap textures directly. This bumps the version requirement to 3.5.0 and makes it sorta-possible to play with software rendering without seeing "invisible pickup models".
Re-ran all textures through optipng.
All add-ons have been updated accordingly.
