string change in gnome-utils

[Emmanuele Bassi <ebassi gmail com>]

hi all;

in order to fix bug #399859, I've added another string to gnome-utils:

  gnome-screenshot/gnome-screenshot.c: _("No effect")

and changed the description of the --border-effect switch to:

  N_("Effect to add to the border (shadow, border or none)")

also, I've had to change the 'border-effect' key description in the
GConf schema because it was out of sync (and has been for a while, or so
it seems).

ciao,
 Emmanuele.
