Commit experimental bugfix for default AI in RCA AI (exerimental targeting)

Browse source 
Fix a very old bug making the AI rates targets as if they were all
reachable in 1 turn. AI should now prefer targets reachable in 2 turns
against one needing 3 (if same value).

Note that it only affects targets needing more than 1 turn to reach.

This also make "complex targetting" works and should make the AI pick
the best unit to reach the best target (probably begin by sending
scouts grab undefended villages)
