add trigger_hurt to screw,
give humans more hp for secret (150hp),
fix screw exploit

fix a chance where after rainbow road final tp zombies will still have a "green orb" speedboost-adjust rainbow road shader and particles a little bit for visibility sake

fix bullet bill sound effect not stopping
rainbow road lag... not sure what's causing that on servers, my guess is effects shader - change rainbow road to complex instead
rainbow road particles were at default particle allocation, optimize that, which should also help a bit with fps and memory
forgot to do asset cleanup - reduce filesize, optimized mipmaps
