[WIP] Christmas Tiles

[Lizandra]

For this work I used stuff that was not created by me: the snow tileset and the candy cane icon

I think the mistletoe door, the Christmas wreath door and the candy wooden sign are mostly done, but I'm not sure about the toy train wooden sign.

Anyway, I'm not intending to keep on with this work, so I'll leave it to anyone who wants to contribute.
