GTK: Don't display bookmark right click menu when bookmark bar is hidden.
GTK: Don't display bookmark right click menu when bookmark bar is hidden.

event box is connected to the button-press-event, if you right click under the
location bar or the browser action icons, you'll show the bookmark menu even
if you have it hidden.
