added sprite rendering and collision, it was stupidly simple

also rectangle collision is coming along pretty well, although I had to literally cut corners (you collide against corners like you would if you were a square, although now I consider it I could maybe fix that by using the cylindrical collision I used for sprite collision... wait)

might add pen+ to it soon although it might take me a minute to figure out how to work it (i think there's a new thing to automatically trim triangles now, which is pretty sick (trimming triangles as in cutting them when 1+ points of it are behind the player))
