How to score rooms for expansion

[JonathanSafer]

In order to keep track of which rooms have been scored and which ones have not, every room will receive a numerical score. Rooms that are incompatible with expansion (controllerless or can't fit template) should receive a -1. All other rooms should be scored from 0 to 100.

Factors to be taken into account in no particular order.
number of sources
mineral (Botarena only?)(probably only care if it's catalyst)
proximity of 'best' template placement to controller
proximity of 'best' template placement to sources
number of highway rooms in sphere of influence (MMO only)(closer highway rooms are more valuable than farther ones)
distance from nearest friendly room (maybe this should only be calculated when deciding to expand since it is subject to change)(MMO only)
number of swamps under road portions of template?

number of highway rooms in proximity still needed

with remote mining coming up, this should be factored into the score
