[packagekit] New backend: FreeBSD Ports

[Anders F Björklund]

When talking about the existing Portage backend, and
the running of PackageKit on FreeBSD mentioned earlier,
I made a simple new read-only implementation for Ports...

http://www.freebsd.org/ports/

It uses a dispatched ruby backend and portupgrade/pkgtools,
and will install either ports or packages - as configured.
(once it actually installs/removes anything, that is...)

Currently neither PolicyKit (i.e. "One") nor DeviceKit are
running on FreeBSD, so it runs with dummy security framework
and dummy battery framework - for another read-only reason.

I also needed to change the hardcoded "/usr/share/applications"
to look in "/usr/local/share/applications" instead for the
.desktop files, in order for gnome-packagekit to show icons.

PS. With the DB, it takes about 5 seconds to list all ports.
     Which really isn't too shabby for an interpreted language,
     since there are now over 20,000 ports in the collection.
