Add $::lsbdistcodename for backward compatibility
Use $::osfamily instead of $::operatingsystem
Fixing php-fpm sources correctly

* Use /etc/apt/sources.list.d/dotdeb.list instead of main file
* Use $::lsbdistcodename fact to use a proper debian release
* Avoid using sudo (not available on a default debian install),
  as we are running from a privileged user anyway
Linting the whole module

* All OK except classes documentation
* Command string: puppet-lint --with-filename --no-documentation-check .
* @see http://puppet-lint.com/
