Further image preparation for the Extreme Exhibitionist Update

- Widened Moon's 2-cantstrip_a
- Moon's 4-stripping_sad is accidentally a duplicate of 3-stripping_mad,
so I replaced all references to it with ones to 4-stripping_calm
- Rotated some of GPC's images
- Made new text file for Mettaton's sitting images, but correct
crop_pixels value not yet found
