- create the printer/ hierarchy

- split services related stuff into services.pm & printer::services,

- move things that've nothing to do with printers into common.pm
  (alternatives, permissions, ...)

- move eveything related to cups, gimp-print, detection,
  {star,open}office to the corresponding splited printer:: module

- big consolidation of printer::office (it was obvious there were tons
  of duplication between staroffice and openoffice managment)

- move other stuff into printer::main, printer::common,

status : print.pm has been heavily splited (now one can begin to
understand the little bits).
printerdrake still needs to be splited/cleaned and eventually removed
since printer/printerdrake modules separation is not understandable by
other people

till, in printer::gimp, $lprcommand is neither declared nor setted
nowhere.  idem in mdk9.0 ...
