[PATCH] right-click menu on volume: "Play DVD/Play CD"

[Emmanuel Touzery <emmanuel touzery wanadoo fr>]

Hello,

   In GNOME in general as of today it is not very easy to discover how 
to play an audio CD or a DVD. Of course the CD/DVD will start playing 
when you insert it in the drive, but if the media was already in the 
computer when you booted it, nothing will happen and the user must eject 
the media and reinsert it to let the computer play it.
   Hence this patch that adds "Play CD" or "Play DVD" on the 
right-click on a volume if that volume is a CD or a DVD. Actually this 
responds to a bug where the original requester asked for playing the 
CD/DVD on left click (open), while I simply added the action on the 
right-click menu, the choice left-click action or right-click menu is open.

   The patch is at:
http://bugzilla.gnome.org/show_bug.cgi?id=149224

   As noted in the bugzilla, it is related to the patch 
http://bugzilla.gnome.org/show_bug.cgi?id=308388 to the drivemount 
applet, also allowing to discover easier how to play a CD/DVD (showing 
"Play CD/DVD" for CD/DVD media, instead of "Open", which opens nautilus).

   For both patches, there is some code duplication with 
gnome-volume-manager, but I don't know another way. The patch for 
nautilus was initially written on 2.10 then ported to CVS by 
copy-pasting, but I didn't try it on 2.11 because I don't have the 
dependencies to build it. However I'm convinced it'll work on 2.11 too, 
nothing that seemed relevant changed.
