In Git 1.6 and later gitk is in $prefix/bin while git-gui and all
of the other commands are in $gitexecdir, which is typically not
the same as $prefix/bin. So we cannot launch $gitexecdir/gitk and
expect it to actually start gitk properly.
By allowing git-gui to locate the script via $PATH and then using
exactly that path when we source it during the application start
we can correctly run gitk on any Git 1.5 or later.

If we are building on Darwin (sometimes known as Mac OS X) and we
find the Mac OS X Tk.framework in the expected location we build
a proper Mac OS X application bundle with icons and info list. The
git-gui and git-citool commands are modified to be very short shell
scripts that just execute the application bundle, starting Tk with
our own info list and icon set.
Although the Makefile change here is rather large it makes for a
much more pleasant user experience on Mac OS X as git-gui now has
its own icon on the dock, in the standard tk_messageBox dialogs,
and the application name now says "Git Gui" instead of "Wish" in
locations such as the menu bar and the alt-tab window.
