parts of gnome want vte3, and yet some other stuff (py-vte) still wants vte2.
if we let vte2->vte3 because of gnome, then py-vte will complain, and the
update won't happen.
considering we've set things up so vte2 and vte3 can coexist, the thing to do
is have vte2 update to vte2-newer, let gnome3 pick and install vte3 as well,
keeping py-vte happy and ending with a fully updated machine.
On the way, need to tell quirks AND vte about vte-pyhelper, which vanished
into vte2/vte3 (and again, pick one).
(triggers a bug in pkg_add caching which requires -current, btw ;( )
Solves update issue reported by Mikolaj.
Ports STILL fully locked, this making it in as a vital update thing,
(no don't ask, your silly little update won't make it)
