title: How to pass toolbar attributes to django-summernote SummernoteWidget?
body: <p>I am using django-summernote and I need to have custom toolbar on my form. I already customized SUMMERNOTE_CONFIG setting. But this particular form needs to have another settings. So I am using SummernoteWidget in form. Form is:</p>
  
  <pre><code>class CommentFormAuthenticated(forms.ModelForm):
  
      comment = forms.CharField(widget=SummernoteWidget(attrs={'width': '20%', 'height': '500px'}),)
  
      class Meta:
          model = Comment
          fields = ['comment', ]
  </code></pre>
  
  <p>For example toolbar should have following settings:</p>
  
  <pre><code>'toolbar': [
              ['style', ['style']],
              ['style', ['bold', 'italic', 'underline', 'clear']],
              ['para', ['ul', 'ol', 'height']],
              ['insert', ['link']],
          ],
  </code></pre>
  
  <p>But this way in the doc they are used in settings.py as one of the parameters of SUMMERNOTE_CONFIG variable. So I am trying to implement these settings to SummernoteWidget in form like this:</p>
  
  <pre><code>class CommentFormAuthenticated(forms.ModelForm):
  
      comment = forms.CharField(widget=SummernoteWidget(attrs={
          'width': '20%', 
          'height': '500px',
          'toolbar': [
              ['style', ['style']],
              ['style', ['bold', 'italic', 'underline', 'clear']],
              ['para', ['ul', 'ol', 'height']],
              ['insert', ['link']],
          ]
  
      }),)
  
      class Meta:
          model = Comment
          fields = ['comment', ]
  </code></pre>
  
  <p>But toolbar doesn't change at all. What is the right way to pass these settings to the SummernoteWidget?</p>
