Backport some changes from development branch:

- 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
