add new studio sprites

Adds six new studio sprites.  One downside is we're running out of good start locations, and the way things are set up, each sprite has a singular start location, meaning you can get crowded sprites even if using only one or two.

Good thought.  It would throw things off.  It looks like spriteStartingImage is never higher than 4 though, so we should be fine :)
