gedit string change

[Jesse van den Kieboom <jesse icecrew nl>]

Hi,

By fixing bug 143646 (http://bugzilla.gnome.org/show_bug.cgi?id=143646)
we needed to change a string found in
gedit/gedit-io-error-message-area.c:

_("This file (%s) is already opened in another gedit window.") instead
of _("The file %s is already open").

There has also been a little string change in
plugins/filebrowser/gedit-file-browser-widget.c to match the strings
used by nautilus:

N_("Go to the previous visited location")
N_("Go to the next visited location")

and one addition
N_("Open the parent folder")
