Support looking up Plasma services.
Review Request #101717 - Created June 21, 2011 and submitted
This patch implements lookup of Plasma services in Apper master. It requires this PackageKit commit: http://gitorious.org/packagekit/packagekit/commit/9345191c9041b9cafd5ecdf89d1f84772a92adb7 The interface I added is a generic InstallResources which already got approved by Richard Hughes and committed to gnome-packagekit: http://git.gnome.org/browse/gnome-packagekit/commit/?id=a9196b7b993e72916afae5752c06851adbc8a869 (Richard didn't want yet another Install*Resources method added. Instead, we now have an extensible API which can support more service types later.)
I verified that everything compiles. More testing will have to wait until the Plasma-side code which actually uses the stuff is ready.
