gnome-control-center (Wacom) freeze break request

[Bastien Nocera <hadess hadess net>]

Heya,

We've added configuration for Wacom graphic tablet in GNOME 3.2, but the
panel is always present, whether or not we have a Wacom tablet, and,
even more annoyingly, we can configure the absent tablet.

The patch in this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=657424

Adds 3 strings, and a link to the Bluetooth panel to setup a new tablet.
A screenshot of the UI is available there as well.

Cheers
