Todo for 0.27:
    - Fix the constant "CPU complete" dialogs when low on money.
    - Record more things (times that techs are complete, etc.)
      for both "scores" and general statistics:
        # saves.
        # Bases constructed (per type)
        # Bases discovered (per type per news/science...)
        # Bases destroyed (per type)
        # Money earned (huge)
        # Time to completion
        # of upgrades for all bases
        # per-tech time to completion (from day 0 to start, then time to completion)
    - Add more items.
    - Get more items translatable.
    - Try out pygame.key.set_repeat()
    - Make construction that requires CPU a research option when needed.
    - Building CPUs should tell you how much CPU you get from it.
    - Building bases should tell you the real discovery rates, not the defaults.
    - Actually use the events we added.
