title: disable future dates in angular-bootstrap-datetimepicker
body: <p>I am unable to disable future dates.</p>
  <p>Using <a href="http://dalelotts.github.io/angular-bootstrap-datetimepicker/" rel="nofollow noreferrer">angular-bootstrap-datetimepicker</a></p>
  <pre><code>&lt;datetimepicker data-ng-model=&quot;user.join_date&quot; data-datetimepicker-config=&quot;{ startView:'day', minView:'day' }&quot;    /&gt;
  </code></pre>
  <p>Tried adding <code>this.future = false;</code> inside <code>DateObject()</code> of directive without any success...</p>
  <p><strong>EDIT</strong></p>
  <p>Found that I can use <code>before-render</code> and then make <code>selectable=false;</code> for future dates.</p>
  <p>Trying to implement.</p>
  <p>Thanks for any help!</p>
