New Feature: 2 new Iron Man game modes (by anv)

- Selectable at campaign start under "Extra Difficulty" label
- Soft Iron Man: No saving when in turn-based combat. Can save with enemies around (in sector) but only if still in real-time mode.
- Extreme Iron Man: No saving, except punctually at midnight - save screen opens by itself, so Player won't accidentally miss saving time window. Besides Player's save, game will be auto-saved at midnight too if auto-saving is on.
- New ja2_options.ini values for Extreme Iron Man setting: EXTREME_IRON_MAN_SAVING_TIME_NOTIFICATION,
