auto-save every turn for AI-AI battles

[WildCatNL]

When testing maps/scenarios by having the computer play both sides, it would be very helpful if the game were automatically saved on the end of a turn (for one side, or for both sides).

Currently, the game only saves the initial state. The user preference of auto-saving every turn has no effect.

Without the game auto-saving progress, I'm forced to attend the game during the complete run, checking for abnormalities. If the game would save turns, I leave the game run unattended, and only inspect saved game states, possibly starting with the last turn.
Having auto-saves would also be helpful in reporting any potential bugs found.

(It's probably a setting you already use for development purposes).
