Label options generate incorrect markup

[eoliphan]

Hi, I tried adding a leftLabel to a field and got the following:

<div class="ui labeled fluid input field required">   
      <label for="Y5WfHhnv2Cj2QQBr3">       
          Min raise amount       
      </label>

      <div class="ui label">$</div>

    <input type="number" name="minRaiseAmount" leftlabel="$" id="Y5WfHhnv2Cj2QQBr3" required="" data-schema-key="minRaiseAmount" max="2000000" min="50000">

  </div>

In reviewing the SUI docs, it looks like the 'ui labeled input' class needs to wrap the input and any pre or post labels as well as the input. The 'normal' field tag should go outside of that div but inside the normal 'field' div.

I can try tackling this via a pull request.
