Icons

Getting close!

I've been putting off doing the math for the icons :) Lots of radical threes.

Here we can see the three main icons - * for a city, ! for enemy units, @ for my units. ALH also has icons for ships, taxing, production. It also differentiates between my units on guard vs. not on guard. Not sure how important that is (although I need ships)...
I also still need to add roads and buildings.
