Subject: [PATCH] polkitAgent: Indicate which application initiated a request

Now that the ::initiate signal may contain the PID of the initiating
process, we can try to resolve it to an application and use that to
indicate where a request originated. This should work for well-behaved
applications that only ask for permissions in response to a user action,
but unfortunately not when it would be most useful, that is when the
dialog is triggered "out of nowhere" by a background service ...
