use a resize limit for new events in fullcalendar options

cancel-resize.js

    select:function (start, end) { 
    	var mEnd = $.fullCalendar.moment(end);
	var mStart = $.fullCalendar.moment(start);

	slotParts = calendar.fullCalendar('option','slotDuration').split(':');
	var addDurationToStart = moment(mStart).add(slotParts[0], 'hours').add(slotParts[1],'minutes');

	if (mEnd.isAfter(addDurationToStart)) {
	    calendar.fullCalendar('unselect');
        } else {
             calendar.fullCalendar('renderEvent', {
                start: mStart,
                end: mEnd,
                allDay: false
