	Change Script-Fu error handling to properly use the new error
	message passing in PDB return values:

	* plug-ins/script-fu/script-fu-scripts.[ch]: remove function
	script_fu_error_msg().

	* plug-ins/script-fu/script-fu-interface.c (script_fu_ok): output
	errors of interactive script-fu dialogs directly here with
	g_message().

	* plug-ins/script-fu/script-fu-scripts.c (script_fu_run_command):
	add GError and return the error message instead of displaying it.

	(script_fu_load_script): show the returned error here (and make it
	more specific than the former script_fu_error_msg() did).

	(script_fu_script_proc): return error messages via the procedure's
	return values.

	* plug-ins/script-fu/scheme-wrapper.c
	(script_fu_marshal_procedure_call): if an error message was
	returned from the PDB call, pass it to foreign_error() so it ends
	up where it should (consle, text console or error string).

	* plug-ins/script-fu/script-fu-console.c
	* plug-ins/script-fu/script-fu-text-console.c: set the error
	handler to PLUGIN while interpreting scheme, we handle errors
	from calling back into the PDB ourselves now.
