[Bug 59244] gnome-session logout hang with a composite manager

[gandalfn]

Public bug reported:

Binary package hint: gnome-session

gnome-session logout hang with a composite manager, that is due of justified use of XServerGrab on logout. 
The composite manager also using this function for the screen refresh, Grab of gnome-session thus blocks screen refresh and the logout window does not appear while being open. 
Here small a patch which inactivate Grab/Ungrab on logout when GSM_NO_GRAB_SERVER is defined in .gnomerc.
