Minor AI quibble on VTOLs

[cruise]

Nothing to really fuss over, but having it recorded is always helpful:

On the 2.0.7 version the VTOLs seem to select re-arming pads in build-order preference rather than spatial proximity - playing Little Egypt I had captured and blockaded the central mound and built a patch of rearming pads, but VTOLs assigned to strike towers on the central area always went back to my base to re-arm.

Not a massive problem, but did cut down on their response times to incoming attacks rather a lot...

Workaround: First assign VTOL to nearest Pad, after landing assign it to Sensor
