AI not building power plant

To reproduce: Play skirmish on map Sk-cockate-T1 as Player 1, allied to player 3 (AI). Choose no bases for start.

AI player 3 will not build a power plant. It will build all other buildings normally.

The only way to have player 3 build power plants is by having it die and then ressurect it by giving it some units and energy.

P.S.: I have seen the problem in other situations, such as network games.

It took me a while to realize what the problem was here. The AI keeps trying to build a power generator on top of the hill to the east of the base start position, but there are no ramps up to this hill. It is not an easy bug to fix, either, since the script functions used do not pass enough information to check that such positions are accessible by the droid that intends to build on them. Changing the function parameters will break AI mods, and possibly savegames.

I plan to fix this later by adding a new function to find a location to build on that passes the construction droid as an additional parameter.

(In [10322]) Add new AI script function that gives position to build a structure while checking that
a given droid can build it. This is used to fix #1626 where a power generator
could not be built because the build position function used gave inaccessible coordinates.
