v1.2 - The Spindash Update

So yeah, one day after release, and already an update is in order. XD This version focuses on improving the Spindash, alongside some other changes.

Spindash changes:
-You can now turn around during a spindash, and jumping out of it will carry your momentum.
-You can now cancel a spindash jump into an aerial without double jumping first.
-Spindash hitboxes now have an Angle Flipper of 9, as I felt it was too powerful without it.

Other changes:
-Palettes have been improved. Base palettes have not yet changed so some sprites may still look strange with the alternate colors.
-Preview picture has been changed to one of Sonic's sprites, to keep consistency with my other character mods.
