couple of very minimal changes. runners are now lockstep instead of each having its own bpm (sorry polyrhythms but i ended up not liking that code) and i can erase all runners without having to restart the whole program.
lots of UI to do, lots of things to add. but it's so fun

mostly logic/behaviour changes that aren't really visible. new "directional" tile type allows for runners to warp back to their initial position
