git-gui: Display the full GPL copyright notice in about dialog.

We're a true GPL program, and we're interactive.  We should show the
entire GPL notice and disclaimer of warranty in our about dialog upon
request by the user, as well as include it in the header of our source.
Perhaps overkill, but is recommended by our license.
