Clicking on labels doesn't work for checkboxes and radio buttons

The problem lies in this code block:

// Create a unique id field for checkboxes 
if ($this.attr("type") == 'checkbox' || $this.attr("type") == 'radio') {
  $this.attr("id", $this.attr("id") + '-' + uniqNum);
}

We should also change the "for" attribute of the label in order for the labels to keep working. I'm going to postpone this until #359216: huge memory requirement for view with editable fields. gets in.
