Salt Deserts

(This is an expansion of the post Powdered Salt)

Salt deserts should be a new warm biome that is very abundant on crystalized salt blocks.
Salt deserts are normally found near beachy places and near the ocean.
Salty rivers could be a new exclusive type of river that can only generate in salt deserts, differently than normal rivers these ones are almost entirely made out of crystalized salt blocks.
Salt deserts should be a uncommon biome.
Spawning:
No slimes, skeletons or zombies should be able to spawn in these biomes, but maybe a zombie variant could be added to it.

PS-This post expands in the post Conserved Zombies
Tell me if there's anything i should add ;D
