Oil rigs & oil fields

[evanpelle]

Inspiration: https://www.reddit.com/r/Openfront/comments/1qrbpft/gameplay_idea_mining_resource_nodes/

The idea is to convert factories => oil rigs. When the game starts oil fields are placed randomly on the map. Oil rigs can only be placed on an oil field. This creates strategic points of interest as players will fight to control oil fields.

oil rigs will act basically how factories do now expect they can only be placed on oil fields. No new "oil" resource will be addded.

I think that factories placed on oil fields should produce more gold due to oil being more strategic, this would give players a greater incentive to actually fight for them.

I (and @danielliuguin) would like to be assigned to this feature, so we can attempt to implement it and make a PR.

Currently most wins come from spawning next to nation clusters, could it be programmed so that oil fields always spawn in areas not near nations, to at least give some incentive to not always spawn next to nations?
