title: Fullcalendar add class to weekView
body: <p>I wanted to add a class like ".today-date" to the weekView Table Header in fullCalendar. <strong>Because I wanted to highlight the Today Date Header with a background-color, like the td row is highlighted.</strong></p>
  
  <p>The cell Content of the weekView already have a class ".fc-today .fc-state-highlight".</p>
  
  <p>I try with dayRender function from fullcalendar, but my Javascript understanding is a bit to low... I hope someone can help the noob ;)</p>
