It is a tough call. Saving AI data gives us a better tool for debugging,
but at the cost of inflating the size of the savegames.

The reason is that when the savegame is created, things may have changed
since last time the AI generated its data, and hence, a regeneration of
these data will give different results.

Again, encapsulating the AI's turn actions into an atomistic sequence
where all data is either stored for later and therefore saved, or thrown
away and regenerated, and no in between cases like now, will significantly
clean up this issue.
