Tall Grass Generation

Currently tall grass only occurs due to grass skills. This could be used in level generation for a little more variety.

I do think that if we have a type of level tile, we might as well use it. We might need to do some testing in 3d to see if it looks reasonable, or if it looks like grass that tall would only come from a spell. But I say lets go for it, for now.

I added tall grass generation, and it seems to be in the level, but I don't think we visually distinguish between tall grass and normal grass? I'm not really sure.

Tall grass has an animation - however, we need another entity type for tall grass to display the other animation. This would need to be handled along with grass for removing the entity when the tile is modified (grass is removed).
