Fix: now compatible with the latest libraries

  the script has been updated to be compatible with more recent
  versions of:
    http-conduit-browser
    unix
    text

  at the same time, the function are more generic (working on
  StringLikes rather than just Strings) thus interacting in a
  cleaner way with tagsoup, etc.
Refactoring: generating statistics

  refactored the way statistics are generated and added new
  categories (Restaurés, Déplacés)
Refactoring: extractAllKramails now using MapM

  extractAllKramails used to be defined by primitive recursion on
  on the page numbers. Which basically amounts to a: forM [1..10]
  We now use the second, much less verbose version.
