title: Django BooleanField does not display label
body: <p>I am fiddling around with Django forms and Django Crispy Forms (using Bootstrap as my theme).  I defined two fields:</p>
  
  <pre><code>test1 = forms.BooleanField(label='Some label here', help_text='help text here')
  </code></pre>
  
  <p>and</p>
  
  <pre><code>test2 = forms.CharField(label='another label', help_text='more help text')
  </code></pre>
  
  <p>When I render my form, the test2 field shows the label like:</p>
  
  <pre><code>another label: &lt;input box&gt;
  </code></pre>
  
  <p>with 'more help text' underneath.</p>
  
  <p>However, for the test1 (BooleanField), the label seems to change the value displayed after the text box, i.e.</p>
  
  <pre><code>[] 'Some label here'
  help text here
  </code></pre>
  
  <p>Is there a way to make it display more like:</p>
  
  <pre><code>Some label here []
  help text here
  </code></pre>
  
  <p>Thanks!</p>
