- "fat" version uses repacked (zip -0) archives; also separate "data"
  and "themes" folders
- "slim" version doesn't use any external themes (for speed reasons)

 Themes handling is quite slow - each theme must be depacked, each one contains
 quite a few XML files to parse and quite a few images to load/convert. That's
 the reason why the built-in one is used as default, it dramatically speeds up
