Customization progress (Patreon)

Since I've basically been out of the game for the last week and will remain as such for a couple more days, I figured I'd at least share what I was able to do before being indisposed.

The palette swapping code has been significantly improved, and now allows for special toggle features on some characters, like the eyelashes on the one above. Other obvious features, like changing the head/outfit are functional, but lacking sprites for certain directions. It's exciting regardless!
