script commands

addspritedef, addspritedef2, and removespritedefs.
it would function like tiledefs, only instead of effecting the tileboard, it would effect the sprites.png.

actionrconline would also be fun, and rcchats (rather rcchat) wich returns the last said rc chat text regardless of weather it starts with /npc or not (or if it was even said by an rc).
