Suggestions: Map coordinates & game assets

I'd love to build a web app for this game to help players find resources on the map, but 2 things make this difficult. First, there isn't a displayable map coordinate system. Adding an accurate lat/lon or similar coordinate or grid system would help users find specific items. Second, it would be great if you made available some of the game assets, like item icons, that could be used in fan-made web apps.

Great job so far! Loving the game and all the recent improvements!
