Update 2.85.0: new build and unit menus

MESHFALL · published · build 26368966

- Each menu is now one row of large cards, with bigger pictures so you can find things at a glance.
- Every card shows its shortcut key and a bar along the bottom showing how much of its price you can afford right now.
- Things you can't afford yet have their price in red.
- The build and unit menus open as one wide strip above the bottom bar, so they cover less of the map.

Thanks for playing, and keep the bug reports coming.
