/*
 dialog messages
 
 takes a messages object formatted the same way drupal messages are, ex:
	var my_messages = {
		status: [
			"message 1",
			"message 2"
		],
		error: [
			"error 1"
		]
	}
 and an optional options object which can extend the default jquery dialog options for messages,
 as well as an auto_close parameter which, if set to a numeric value > 0, will auto close the
 messages dialog after auto_close seconds IF there aren't any error messages. ex:
	var my_options = {
		modal: true,
		auto_close: 3
	}
	
	dialog_messages.create(my_messages, my_options)
