Provide UNR session for desktop

Registered by Martin Pitt

Provide an easy way to add a session type that runs the UNR components, so that desktop users can use the UNR UI on their desktops if desired. This should work similar to the already existing stracciatella session.

 * Please remove the UDS notes below, if/once they are completely integrated into the spec.
 * gconf path: Parsing Xsession.d/* for environment variables doesn't sound efficient, robust, and even if it would work. Can't desktop-une instead install an additional tree like the already existing ones in /var/lib/gconf/ ? Alternatively, add it to gconf proper, so it will be inert when une is not installed.
 * Please settle for one package name (desktop-une-session vs. une-session)
 * Please add work items

 * the GL test should be triggered, as efficiently as possible, in one of the session setup scripts. We can also do it in netbook-launcher, but the window manager may already have given up by the time we're started. One trick may be to have a command line option in netbook-launcher, to just do the test, and then stop. The trick here is that the launcher would already be pre-loaded and the second invocation (in the session, this time for real) should be accelerated by this initial run
 * for the test plan, i think the key scenario is:
  - log into a desktop session, add a funky applet on the panel
  - log into the UNE session, check that 'Applications, Places, etc.' are *not* displayed, the proper applets are loaded, and funky applet is not
  - log back into the desktop session and check that 'Applications, Places, etc.' *are* correctly displayed, and funky applet *is* too

JamieBennett, 2010-01-08:
* As part of the mobile team need to launch a specific instance of netbook-launcher(-efl) depending on the availability of 3D acceleration on our ARM based platforms. We require that after the availability of acceleration is determined, either the 3D Clutter based netbook-launcher is used or the 2D netbook-launcher-efl is used if no hardware is available.

It was discussed that a possible check for 3D acceleration could be to execute glxinfo | grep 'renderer string'.
