BuildMap - Keep track of all units both mobile and static.

[Error323]

People mostly play vs AI to get some lategame action. Currently the buildlayout of E323AI is very cruel: "Get the first spot that has atleast a radial spacing of R". This creates really bad deadlocks in lategame, which the engine has to solve (and often takes a lot of time for it).

Instead I'd like to propose a BuildMap that keeps track of all units, both mobil, static and buildings that are queued in tasks (each in different layers). This will also enable the improvement of defense capabilities.

I hope this issue includes the problem when AI builds non-mexes upon metal spots (valid for non-metal maps), then when time comes to build a mex AI tries to build it as close as possible to building which occupies the spot.

Indeed it does.
