Improve THOKA0
By default, the THOKA0 sprite in vanilla is poorly centered. In fact, it's not even a perfect circle. This little minor detail is pretty annoying, and this MR fixes that. In terms of code, all it does is remove the hacky methods used to display the thok object properly. The new graphic uses a real 40x40 circle, with the correct offsets.
Like any graphic modification, you'll need this for it to work, or else the thok won't look right: BetterThokCircle.pk3
