Initial version from 23-05-2011
Changed gitignore to exlude /obj and png files
Version from 24-07-2011
Added sample txt file to point to supertux source data directory

 - Directory can be from installed game or downloaded source
Added imagebuilder script

This script converts the original PNG images from the supertux_0.3.3 source tree into Genesis sprites, with help of ImageMagic

 - For now only the tux sprites and a start with snow tiles
 - The steps taken for each set of sprites is as follows:
   - Create one big PNG with all sprites in one image, to create a single palette.
   - Make semi-transparent pixels solid
   - resize to 50% of original
   - scale down colors to fit a 16 color palette.

TODO:
 - convert 16 color palette to genesis colors
 - create the actual tiles
 - lot's more optimizations
Added php script to convert RGB pallete into Genesis safe colors. (not yet complete)
Added php script to read supertux .sprite files (not complete yet)
Changes to imagebuilder script.

 - updated resize function to use paramaters to copy the final image
 - removed testing code (exit statement)
 - changed function calls from recolor to resize

TODO:
 - There is a bug in ice-tux, less colors because of blue hat. And black background.
