[gtk+/open-with-dialog: 36/53] open-with: add a PackageKit module for online lookup of applications

commit d4e1dd97341468ca2772029335b95a420abe81ca
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Fri Nov 19 18:00:55 2010 +0100

    open-with: add a PackageKit module for online lookup of applications
    
    It's implemented with a GIOExtensionPoint, which has two
    implementations:
    - a dummy one, which just errors out
    - a PackageKit one, which looks up for the specified content type using
      the PK DBus API and GDBus.
    
    The PK module is optional, and can be compiled out at configure time.
    
    TODO: a Win32 implementation of the module.
