	(ephy_embed_event_base_init), (ephy_embed_event_get_event_type),
	(ephy_embed_event_get_context), (ephy_embed_event_get_modifier),
	(ephy_embed_event_get_coords), (ephy_embed_event_get_property),
	(ephy_embed_event_has_property), (ephy_embed_event_get_dom_event):

	* embed/mozilla/mozilla-embed.cpp:
	* src/ephy-window.c: (popup_menu_at_coords):
	* src/popup-commands.c: (popup_cmd_copy_link_address):

	Make EphyEmbedEvent abstract, implemented by MozillaEmbedEvent.
	Port callers to the new api.
	Fix some callers in src/ which were using private fields of
	EphyEmbedEvent struct.
