		Fix bug #2882, "Reverse preference for external content"
		"Block external content" was the only negative preference
		along the other "Enable ..." positive ones, but also had
		several shortcomings, in that it only blocked user-
		requested interactions, like
		- prevent clicking on links
		- prevent right-click/Download link
		- prevent right-click/Save image
		But NOT
		- prevent auto download of images (that's controlled by
		  Auto-load images)
		- prevent auto download of javascript (that's controlled
		  by Enable scripts)
		- prevent auto download of applets (that's controlled by
		  Enable java)
		- prevent auto download of css (that can't be disabled)
		New preference to replace it is "Enable inner navigation"
		and allows to control whether one can click on links to
		navigate inside Fancy viewer. If disabled and "Open in
		external browser" is set, links will be opened in external
		browser; else nothing will happen. In any state of these
		preferences, right-clicking and choosing "Open in viewer"
		or "Open in browser" will do what asked.
