Subject:    [PATCH] contrib/difftool: Don't repeat merge tool candidates

git difftool listed some candidates for mergetools twice, depending on
the environment.

This slightly changes the behavior when both KDE_FULL_SESSION and
GNOME_DESKTOP_SESSION_ID are set at the same time; in such a case
meld is used in favor of kdiff3 (the old code favored kdiff3 in such a
case), but it should not matter in practice.

Hi Junio

This is based on top of Markus's kompare patch:
	"contrib/difftool: add support for Kompare"
	http://article.gmane.org/gmane.comp.version-control.git/107883

This syncs difftool up with the mergetool patch that's in 'next':
	"git mergetool: Don't repeat merge tool candidates"
	http://article.gmane.org/gmane.comp.version-control.git/106669
