Colors Ultimate

Originally started as an internal branch by @Lach, containing a couple of skincolor-related tweaks to go with character resprites, but it ended up going way beyond that:

• Added 44 new skincolors
  • Includes new default colors for Knuckles (Pepper), Amy (Taffy) and Fang (Mauve)
  • Each Chaos Emerald now has a matching skincolor: Emerald, Crystal, Sapphire, Aquamarine, Topaz, Garnet and Meteorite
• Changed a couple of existing skincolors
• Simplified the way invcolor works (Resolves #496 (closed))
• Fixed Mario mode's invincibility color cycle
• Improvements to color selection in the Player Setup menu
  • Added a grid view to easier navigate through large amounts of colors, accessed by pressing Enter on the Color... option
  • PgDown/PgUp cycles through both regular and grid view faster
  • Added development shortcuts to Player Setup menu:
    • Pause/Break to pause player's walking animation
    • Insert to change background color to the current skincolor's invcolor
• Tweaked NiGHTS link colors & added even more vibrant colors after obtaining a link of 600
• Fixed NiGHTS score sprites not changing color, they now cycle through the link colors (Resolves #745 (closed))
