Desktop menu items!

[Ryan C. Gordon]

MojoSetup can now install (and uninstall) desktop menu items 
(specifically, it can put entries on gnome-panel's Applications menu, 
and whatever else xdg-utils supports). This support will eventually 
extend to the Windows "Start" bar, etc, but for now, it's just a Unix thing.


To use, you just make sure you install an icon with the rest of the game 
and add a Setup.DesktopMenuItem section to your config file.

Read the new docs on it here:

http://svn.icculus.org/mojosetup/trunk/docs.txt?r1=481&r2=486&p1=trunk/docs.txt&p2=trunk/docs.txt

And the specific duke3d changes required for this...

http://svn.icculus.org/mojosetup/trunk/examples/duke3d/scripts/config.lua?r1=481&r2=486&p1=trunk/examples/duke3d/scripts/config.lua&p2=trunk/examples/duke3d/scripts/config.lua


There's more to do: you can't define file extensions that should be 
mapped to your application (just mimetypes...but we don't let you map 
extensions to mimetypes yet...), you can't install new submenus, 
xdg-desktop-menu needs to be obfuscated, etc, but this is everything you 
would need for most games you'd want to ship on Linux.

Questions and bugs: ask here.
