title: Boostrap datepicker, disabled dates dynamically each month
body: <p>I can disable dates with:</p>
  
  <pre><code>$('#datepicker').datepicker({
      todayHighlight: true,
      datesDisabled: ['03/06/2017', '03/21/2017','04/14/2017']
  });
  </code></pre>
  
  <p>but with my use case, since you can go over the year by the calendar, I can have 300 disable days out of 365 in 2017 and 200 disabled days out of 365 in 2016. </p>
  
  <p>I want to optimize, imagine after 5 years, he could have 2500 disabled days to load.
  Someone know how to do it dynamically, I mean, each time a change the  current month.</p>
  
  <p>Or another way to do this?</p>
