give the apa ships the ability to repair and resuply other ships

the downside your ship should not be able to move while you resupply/repair
and that apa ships resupply/repair is limited to points in the skills
the amount of point repaired should not be more then its maximum hull points
if your out of points to resupply/repair the apa has to go to a friendly base and recharge the abbilty to repair/resupply
