Some civilizations have their kit built around certain terrain, like Iroquois with trees and Songhai with rivers. Those two currently have their start bias set to "forest/jungle" and "river" respectively, but Incas only have a hills bias, which does not guarantee them any nearby mountains, which boost their UI and have good yields themselves.
I've added a brand new table Civilization_Start_Prefer_Mountain for this specific use. If we add Incas to this table, the start positioning code will give value to nearby mountains (otherwise junk tiles = minus points) and they should start near mountains much more often. They'll also be guaranteed to start in a region with the most mountains.
However, this could be a buff to the Incas and people may not like them getting "special treatments" (Venice already gets some, btw), so I'm making a poll here.

Technical stuff for modders below:
I've also added the Civilization_Start_Prefer_Snow for a snow "bias", which gives a higher score for snow, tundra and coastal tiles and a lower score for grassland and plains, while making the civ start in a tundra region with the most snow. @pineappledan please take note
New priority:
Snow > Mountain > Priority Coastal (Venice) > Coastal > River > Region Prioritize > Region Avoid
Currently it's only possible to give ONE civ a mountain bias and ONE civ a snow bias. Not technically difficult, I just don't have time for that for now.
