Map: Modified Parganos map file and image

[llamabeast]

Attached is:

- A modified .map file for Parganos, which aims to make it a much fairer map to play on. Previously one nation could easily be stuck in vast expanse of wasteland, while another sat cheerfully in the farms. The distribution of terrains is now much more even, while attempting to maintain some correspondence to the picture.

- A modified image file. I found the one with the game to be a bit washed out. In this one the borders are more visible and the colours more vivid. You should back up your old parganos.rgb file before unzipping this one into your maps directory.
