 Code uses the titlealert jQuery plugin, options are below
 interva 500	The flashing interval in milliseconds.
 originalTitleInterval null Time in milliseconds that the original title is diplayed for. If null the time is the same as interval.
 duration 0 The total lenght of the flashing before it is automatically stopped. Zero means infinite.
 stopOnFocus	true If true, the flashing will stop when the window gets focus.
 stopOnMouseMove	false If true, the flashing will stop when the document recieves a mousemove event (i.e. when the user moves the mouse over the document area, regardless of what window is active).
 To use find titlealert in the code and make as so
 $.titleAlert(mChatNewMessageAlert, {
	 requireBlur:false,
	 stopOnFocus:false,
	 duration:4000,
	 interval:700
	});
