Cities n' Squares

Umanità now has square tiles, I've modified the hexagons to be squares by joining seven adjacent hexes together and then cutting out a square. However, at the moment the squares do not line up perfectly at their edges so some adjustment is needed.

No tile edges yet, but that should be easier with squares. Before getting to that, there is much work to be done on the game engine, city's populations need to be able to grow, the units dart around immediately when given orders - I only noticed that after a recent computer upgrade. Also there are some glitches in loading and unloading units from boats, still haven't figured out any good way to handle this efficiently and with a minimum amount of code.

More importantly, there are also some much needed low level refinements and efficiency improvements to be done.

Here's a pic of the city interface in its current state:
