(svn r11106) -Add: added .tar support; you can pack all files in your data/ dir in how ever many .tar files you like, keeping the dir-structure equal to the unpacked version, and OpenTTD can handle them just like the files were unpacked

Browse Source 
-Note: useful for GRF-packs and 32bpp PNGs. Don't forget to keep the dir-structure alive for 32bpp PNGs!
  -Note: file-loading-order: search-paths, .tar-files in the order found on disk (can be anything at all, don't depend on it.. use 'openttd -d1' to see which order they are added)
