Proposal of a crossdesktop interface to query several properties about the state-of-the-desktop

Errmm... talking about "crossdesktop" we mean that:

- Run Kaffeine on Gnome: ask the current state of the system (it depends on 
the gnome _current_ state of the system ! not on a _saved_ config file by the 
kde libraries).

- Run Totem on KDE4: Plasma will see that Totem is playing a full screen 
movie, and it shouldn't start the screensaver, instead of totem 
sending "fake" key press events (I assume it does so or a hack like that 
[kaffeine does]).

- And more more examples... is not all about a saved config file that our KDE 
apps read and write, is about the current state of the desktop.

Well, our idea is only locally. The idea as explained is that you ask the 
freedesktop interface, and you have a daemon running (it doesn't matter if on 
the gnome or kde desktop), you get a response depending on the current state 
of the system and you take decisions based on that.
