	* src/ephy-window.c: (popup_menu_at_coords),
	(idle_unref_context_event), (set_context_event),
	(embed_popup_deactivate_cb), (get_name_from_address_value),
	(show_embed_popup), (ephy_window_dispose),
	(ephy_window_get_is_print_preview),
	(ephy_window_get_context_event):
	* src/ephy-window.h:
	* src/epiphany.defs:
	* src/popup-commands.c: (popup_cmd_link_in_new_window),
	(popup_cmd_link_in_new_tab), (popup_cmd_bookmark_link),
	(popup_cmd_copy_link_address), (save_property_url),
	(popup_cmd_open_link), (popup_cmd_set_image_as_background),
	(popup_cmd_copy_image_location), (popup_cmd_open_image):

	Add public function ephy_window_get_context_event() to get the
	EphyEmbedEvent for the current popup menu, instead of using an
	undocument g_object_get_data() call. Also fixes bug
	#310910.
	Don't printf NULL; fixes bug #309796.
