piwik (1.12-2) stable; urgency=high

  * reverted the removal of licenses files so piwik if full vanilla. this was
    necessary (sort of) because piwik checks the md5 of these license files
    and complains if missing during the installation, the system check or
    upgrade
  * updated lintian rules file even if it doesn't find all license files
  * updated Makefile accordingly
