SotBE S10: slight change to a message

The original version only makes sense if the AIs are winning at the
time.  The new version works either way.
SotBE S10: have AIs target only Inarix, not all saurians

Also set target value for Inarix equal to that of Kapou’e.  Otherwise
it is pretty much impossible to save Inarix.
SotBE S10: decrease value of villages for AI sides
SotBE S10: don't give huge unannounced gold bonus to AIs at turn 8

Instead, give AIs all the gold from the beginning, but stop recruiting
after a little less than half of it is spent.  At turn 8, start
recruiting again with the remaining gold.
