City and Barb Camp Placement Fix

Prevents cities from being founded, and barbarian camps from spawning, on Snow Tiles or waterless Desert Tiles (not next to an Oasis, River, Lake, or the Coast) for realism's sake.

Snow Tiles represent Antartica-like conditions (land buried under miles-thick ice sheets), which cannot support even primitive encampments, let alone cities. There is a similiar situation within the deep desert, away from a large water or food source. Desert cities in real life are near the coast, rivers, or oases, not in the deep, empty desert (ex: middle of the Sahara).

Note: If the Honor tree is taken, the game will still tell you about barbarian camps spawning in Snow or waterless Desert tiles. These alerts can be ignored as the camps and the units they spawned are indeed removed after the alert goes out. I couldn't find a way around this. If anyone knows how to prevent it from alerting the player needlessly about such camps, please let me know how.
