About The Pull Request
This PR reorganizes all mouse pointers icons in the codebase into a single folder under /effects, and removes 4 unused mouse pointer icons, all of which are remnants of the Clockwork Cult.
Also removes one rogue white pixel in blind_target.dmi.
Why It's Good For The Game
Better organization and less space taken by unused icons.
