Autotilesets for Tileset Variants

[Eauix]

This is meant to be a complement for #3082. As the game will soon support multiple autotilesets per tile, this request is focused on adding new autotilesets for many tileset variants in the game that couldn't have autotilesets before due to them sharing the same tile IDs with other tilesets.

The ice floor special tiles still need some tweaks, other than this, it's pretty much done

The autotiles overhaul is ready for review and testing

aaaaaah i tested it again and it works ! ! ! !

Tested, this works, however I would prefer if the autotile started at 1 and not 0. 0 is at the other end of the keyboard. just a small detail.

Additionally, perhaps the 0-9 selected should also work for NUMPAD keys
