[gnome-settings-daemon] wacom: invert TPCButton setting.

    wacom: invert TPCButton setting.
    
    Wacom's TPCButton option which this setting emulates is to enable Tablet PC
    stylus behaviour when on. The property "Hover Click" works the other way
    round, i.e. if Hover Click is _enabled_ this is the equivalent of TPC
    behaviour _disabled_.
    
    Bug exposed by commit xf86-input-wacom-0.10.99.1-10-ge0354b9.
