	* mail-format.c, mail-display.c: Now that we're not limited to
	a single GtkHTML for the display, there's no reason to embed
	Bonobo objects for unrecognized content-types in GtkHTML rather
	than embedded them into the vbox directly. So do that.

	Meanwhile, fix up the handler-selection code so that we can
	declare which built-in handlers are more desirable than external
	handlers and which are less. (Of course, eventually we'll want
	this to be customizable.) Add some cleverness to
	handle_multipart_alternative as well so it doesn't accept an
	alternative which we can display generically over one we can
	display specifically.
