2 - Record more things (times that techs are complete, etc.)
3 for both "scores" and general statistics:
5 # Bases constructed (per type)
6 # Bases discovered (per type per news/science...)
7 # Bases destroyed (per type)
10 # of upgrades for all bases
11 # per-tech time to completion (from day 0 to start, then time to completion)
13 - Get more items translatable.
14 - Make it so that double-click is equivalent to 'OK' in dialogs. (rubikcube)
15 - Make translations easier to do. (Phil has good ideas on how to do this.)
16 - Arbitrary resolution, including non 4:3 scales.
17 - Consistent use of stderr and print.
