KPDF HotNewStuff Browser!

Browse source 
It's not yet complete (file dowload and internal notifies are missing) but
the new stuff browser is running. The ui is modeled on an Aaron's mockup.

NewStuff:
  Fetches the providers list (kpdf.kde.org/newstuff/providers.xml), lets
  the user select a provider and displays provider's contents in a KHMTL
  part (for flexibility and eye candy).
  Internally we use KNS' Entry and Provider structures only, doing all the
  transfer operations by hand via KIO::get jobs. Download will be done
  internally too (to give better consistancy in the interface).
  Network timeouts, problems or info messages are notified in a statusbar-
  like widget and we try to keep all information in the dialog, without
  using messageBoxes

Part:
  Added the action and the dialog invocation

Makefiles:
  Link the KNEWSTUFF and KHTML libraries.
