/*
 * FUNCTION ajax
 *
 *	@param	sAction		String representing the URL we will be sending to
 *						
 *	@param	sMethod		Either 'get' or 'post'
 *						
 *	@param	mHandler	Callback function (can be a function or the name of a function)
 *						
 *	@param	sParams		String containing URL-formatted parameters (e.g. 'a=1&b=2')
 *						
 *	@param	<bAbort>	Optional boolean; true forces any previously pending requests
 *						through this function to abort
 *
 *	Example usage:
 *
 *		ajax('index.php?module=mymodule&cmd=mycmd','post','receiveData','value=5');
 *		function receiveData(data) {
 *			//	do something with data
 *		}
 *
 *	You may also define an "ajaxFail" function in your own scripts (not this one!) if
 *	special behavior is needed when the Ajax request fails.
