Small Suggestion: Terrain requirements of bonuses in the Pedia

[cammcken]

Now that we have new improvements for discovering resources, in addition to all the existing ones, I've seen the question answered: Resources may only be discovered on tiles they would normally be placed. Can we have some info in the pedia for where bonus resources can be found, so that we know what we might find? It could make the difference between, say, choosing a desert camp or a wetlands camp.
