Tank images, need to add other two for animation
Made the changing the direction when updating the image less stupid
(also got hung up on a variable which was capitalized in the wrong spot,
ugh). removed the run idea and increased the speed, changed it so that
directions don't change in air but do when on the ground. also,
@direction is now a string
Turns out the tank pictures are identical to one another (i.e. no
animation :( ) committing to fix some git problems
Ok, Im having some serious git problems, we'll see if I can fix it
