title: Single quote in FullCalendar javascript scheduler
body: <p>I can't render correctly single quote (') in the title field, even if I have the string with \ escape character.</p>
  
  <p>This is the code:</p>
  
  <pre><code>            {{for row in rowseventi:}}
                 {
                      title: "{{=row.evento.titolo}}",
                      id: '{{=row.evento.id}}',
                      resourceId: '{{=row.evento.risorsa}}',
                      start: '{{=row.evento.inizio}}',
                      end: '{{=row.evento.fine}}',
                      recurring: '{{=row.evento.ricorrenza}}',
                      // allDay: false,
                      color : '{{=row.evento.colore}}',
                      url: '{{=URL('mostra_evento',args=row.evento.id)}}',
                 },
              {{pass}}
  </code></pre>
  
  <p>I tried title: <code>"{{=row.evento.titolo}}"</code> and title: <code>'{{=row.evento.titolo}}'</code> too (with double or single quote)
  This is web2py python code...</p>
  
  <p>row.evento.titolo is </p>

  <p>or </p>
  
  <blockquote>
    <p>Dall\'Anese Andrea</p>
  </blockquote>
  
  <p>but the result is</p>
  
  <blockquote>
    <p>Dall&amp;#x27Anese Andrea</p>
  </blockquote>
