#191 - Minor optimization to start location importing.  Have the PCX create a subimage directly when getting civ-colored start locations.

Not a measureable difference on my laptop.  Also realizing that the timings are more variable here than on my desktop or Core 2 Extreme laptop, probably because the clocks can vary so much as new computers spin up or down.
