/**
 * New Click Through Action (CTA) script
 * =====================================
 *
 * Functions:
 * ---------
 *	* mm_call(func, arg, action, value, attribute, handler)
 *		Performs Action passing to the Maxymiser server and delayed call of specified function func with agrgument arg
 *		Parameters:
 *			func -- function for delayed call; "false" cause no call; predefined functions are described below
 *			arg -- argument of func;
 *			action -- action name; "false" means no action
 *			value -- action's value
 *			attribute -- action's attribute
 *			handler -- function for additional action collecting; "false" or mm_empty_handler mean no additional handling
 *
 *
 *	* mm_tag(obj, action, value, attribute, handler)
 *		Adds handlers to the hyperlinks and forms
 *		Parameters:
 *			obj -- object to tag; should be form or link;
 *			action -- action name or false
 *			value -- action's value
 *			attribute -- action's attribute
 *			handler -- function for additional action collecting; "false" or mm_empty_handler mean no additional handling
 *
 * Predefined functions for delayed calls:
 * --------------------------------------
 *	* mm_followLink(uri) -- moving to specified location
 *	* mm_formSubmit(form) -- specified form submitting
 *
 * Settings:
 * --------
 *	* mm_js_in_href -- defines behaviour when link's href property contains "javascript:..." structure;
 *		possible values are:
 *		'ignore' -- to do nothing; acceptable when scripts performs form.submit() call
 *		'action' -- sends action on event; useful when script changes document.location.href property
 *	* mm_cta_name -- contains part of the script name; is used for auto self full URI retrieving.
 *
 * Note:
 * --------
 *	Script doesn't work for some page in some browsers ( Opera8.5, IE6)
