xfce4-session updates: dbus interface!

[Brian J. Tarricone]

Hi all,

I just made a pretty huge commit to xfce4-session: we now have a D-Bus
interface with some limited amount of remote control.

Since line wrapping in email kinda sucks, I put up a text file with
some example usage from the command-line using dbus-send:
http://mocha.xfce.org/~kelnos/testing/xfsm-dbus-examples.txt

And the full interfaces are here:
http://svn.xfce.org/svn/xfce/xfce4-session/trunk/xfce4-session/xfsm-manager-dbus.xml
http://svn.xfce.org/svn/xfce/xfce4-session/trunk/xfce4-session/xfsm-client-dbus.xml

Please note that this is preliminary -- I'm still fleshing things out,
so the interface could change at any time.
