Use ne gnome-session 2.24 features to include netbook-launcher in GNOME session

[Luca Ferretti]

Gnome Session 2.24 provides new cool features to add client to a session and manage it. See [1] for full description.

In order to make netbook-launcher a good gnome-session citizen, we should/could:

 1. provide a netbook-launcher.desktop file installed under $prefix/share/applications with relevant keys (see below)
 2. provide a /desktop/gnome/session/required_components/launcher GConf key (value: netbook-launcher) to include
    netbook-launcher as required session component.
 3. add "launcher" to /desktop/gnome/session/required_components_list GConf key and remove "filemanager" when the user switchs to Netbook mode
 4. change netbook-launcher code in order to set RestartStyleHint=GSM_CLIENT_RESTART_IMMEDIATELY.

Note that point 3 should be perfomed by Switch Desktop Mode capplet, not by netbook-launcher itself.

Currently the window type is yet _NET_WM_WINDOW_TYPE_DESKTOP.

If I'm right, the netbook-launcher.desktop file should be something like:
#################################
[Desktop Entry]
Type=Application
_Name=Netbook Launcher
_Comment=UI to launch application in netbbooks
Exec=netbook-launcher
Icon=netbook-launcher
NoDisplay=true
X-GNOME-Autostart-Phase=Desktop
X-GNOME-Provides=launcher
X-GNOME-Autostart-Notify=true
X-GNOME-Autorestart=true
#################################(

Of course I'm not totally sure about this, I've to read [1] again and again, but I think this is the best and proper way to include netbook-launcher in gnome-session.

PS the same approach should be used in maximus, I'll open a similar bug

Stop reading my mind Luca :-). Tagged as "intrepid" as that's when we'll get the new gnome-session.

Regarding Maximus, it already talks to the desktop session to do the same thing. However, at the moment it uses the old method using GnomeClient. When we branch after 0.1, I'll update trunk to target Intrepid & the new gnome-session.

[Neil J. Patel (njpatel)]

Added extra autostart flags to both launcher and maximus. Not making them a part of the gconf session (using autostart files instead) because they remain optional and desktop-switcher expects the autostart files to be in place to do it's job. Maybe switch over to full gconf for Jaunty+1.

Commited to trunk.
