In BS3, inline checkables ONLY have the *-inline class

In Bootstrap 3, when radios and checkboxes are inline, their documentation has the class being **only** `checkbox-inline` and `radio-inline`.  They shouldn't **also** have `radio` or `checkbox`.

From [their docs](http://getbootstrap.com/css/#forms-controls):

```html
<label class="checkbox-inline">
  <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="radio-inline">
  <input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
