barbarian does not reclaim nor resurrect Thors or Titans

[dzosz]

the t3 wrecks were left completely ignored in AI's base. at the same time mammoths and tzars at the same map position were being resurrected. I gave it about 3 mins and nothing changed.

• ai level was set to high
• bar engine 105.1.1-1544-g058c8ea105
• tested on a small map with small metal amount but late in game (Great Divide v1)

BARbarIAn got few pathing fixes recently, maybe it changes current state of deals.
But as resurrectors don't have build-options it could benefit from separate behaviour handler: treat 10-20 rezzers as single group. Currently each rezzer is considered as builder and assigned tasks individually.
