mcresconvert.sh - a shell script to convert MC resources to Minetest

Usage: just run the shell script - without any options it will find
all your MC texture and resource packs and convert them, and put them
in your minetest textures folder.

If you wish to convert a specific file only (has to be zip format), then
pass the path to the script as argument and set the NOGUI envvar:

  NOGUI=1 ./mcresconvert.sh ~/Downloads/texturepack.zip

Dependencies: zenity(optional, but recommended), ImageMagick, unzip
