[RFC/PATCH] git-gui: add a .desktop file

[Jonathan Nieder]

From: Todd Zullinger <tmz@pobox.com>

Most X desktops use files following the Desktop Entry Specification
for menu entries.  Provide a .desktop file for users and distros to
install in the system menu to make git gui easier to find.

Caveats: this patch does not include Makefile rules to actually
install the .desktop file; they can come later.  Such Makefile rules
would need to change the Icon= line to avoid hardcoding a /usr
prefix.

That's a good idea.  How about something like this, to start?

Installing to /usr/local/share/applications or /usr/share/applications
is not right for a program that is being installed for an individual
user.  I suppose $HOME/.local/share is a good default in that case.
Is a makefile supposed to check ifeq ($(prefix), $(HOME)) to take care
of that?

xdg-utils includes an xdg-desktop-menu helper which supports a --user
/ --system option that will presumably install to the right place, and
it is even nice enough to run update-desktop-database when done.
Unfortunately, it lacks DESTDIR support, so I don't think we can use
it.

The xdg-desktop-menu documentation suggests installing icons in some
centralized place with xdg-icon-resource.  The supported icon formats
are xpm and png.

So this is rough, but I still think including it would be an
improvement in the current state.  Thoughts?  Bugs?  Improvements?

Thanks to Todd for writing the desktop file in the first place.  I
hope I haven't broken it too much.
