redo order in which the plugins are searchedv0.22.49

	Now that this verifies the plugin will load by
	os.Exec() loading the plugin, this bypasses the current
	problems with GO not being able to retry loading the
	plugin. Now it can return to testing the ones that
	were built locally by the user before the system
	or distribution packaged default plugins.
