As 343 failed to fix the framerate issues caused by grass I have now removed it, sacrificing aesthetics *sob* for gameplay. I don't feel any chugging moving around the map now but will require a bit of play testing to make sure.

I added a sword ghost for a bit of fun but also a few splinter grenades around the place so it isn't too OP. Once again will require a bit of play testing and this may be changed to a better/worse ghost.
