starcraft replay map parser

Reads a raw map extracted from a replay, and parses its data into a perl
hash. Input is given on stdin, and accepts command line arguments for
setting options.

Can also format map tiles to an ascii or ppm picture, as far as I could
determine the tile identifier. It handles Jungle maps quite decently
(though all data was set up by comparing output to minimaps and map
thumbnails); especially all data in most Lost Temple maps are defined.

Started on support for other tilesets (not only colors differ, but
apparantly also meanings (ramp = wall for example)), but needs to be
worked out.

After collecting sufficient guess points, hopefully a more
complete/abstract determination can be made.
