patch to make the AI be more defensive

This patch makes 2 thinks:
- Considers defensive units those with flag L_DEFEND_GOOD amb
L_DEFEND_OK. I don't know why the L-DEFEND_OK units are not considered
for when choosing a bodyguard.
- Before attacking, after rampage, the unit checks to see if it can
find a weak city or unit to protect.
I run an autogame and did not see empty cities near enemy
territory... maybe is some luck!
