[Map Editor] Stackable tiles

[Map Editor] Stackable tiles
Add the possebility to stack tiles.
There are a lot of tiles that could work well together if stacked.
Army debris, torches, campfires, ruins. if cycled and put together some of these would make great combinations.
Even stacking two of the same tiletype, ie two ruins could make for an interesting landscape piece.

Preferably you would able to select one tile and 'lock it' before adding add another(So you can cycle through the second tileset until you find a suitable match)
