Free the parsed data prior to calling the modules detach()

	Free the parsed data prior to calling the modules detach()
	routine.  This means that any string that gets parsed by a
	module automatically gets free'd by the configuration file code,
	so that the modules don't have to do it.

	Next step is to remove most of the calls to free() in the
	modules.  After that, if there's nothing in the modules detach
	routine, the configuration file code can clean up the module
	instance, too
