Two more AI bugs

[Hans Ronne]

I have now checked in a fix to the Colonizer/spaceport bug. It was the
"don't build ships without a shore" code that did not work as it was
supposed to. It excluded also air-mobile units. And if something (like your
spaceports) only can build air-mobiles, this spells trouble.

Please check that the game now works as expected. As for the second problem
that you described for the 3rd-age game, I don't know if it is related to
this bug, so perhaps you could check it, too.
