title: Add plugins (power paste) in TinyMce django
body: <p>Hi I am trying to add paste plugin in TinyMce in my django app. 
  Here is the setting.py configuration.</p>
  
  <pre><code>   TINYMCE_DEFAULT_CONFIG = {
  "toolbar": 'mobileequationeditor',
  'height': 360,
  'width': 1120,
  'cleanup_on_startup': True,
  'custom_undo_redo_levels': 20,
  'selector': 'textarea',
  'theme': 'modern',
  'plugins':"powerpaste",
  'toolbar1': '''
         fullscreen preview bold italic underline | fontselect,
         fontsizeselect  | forecolor backcolor | alignleft alignright |
         aligncenter alignjustify | indent outdent | bullist numlist table |
         | link image media | codesample | MathJax |
         ''',
  'toolbar2': '''
         visualblocks visualchars |
         charmap hr pagebreak nonbreaking anchor |  code |
         ''',
  'contextmenu': 'formats | link image',
  'menubar': True,
  'statusbar': True,
  }
  </code></pre>
  
  <p>When I open the model in admin there is an error saying</p>
  
  <pre><code>Failed to load plugin: powerpaste from url https://website.com/static/tinymce/js/tinymce/plugins/powerpaste/plugin.min.js
  </code></pre>
  
  <p>I have tried collectstatic but no new static was collected. 
  Where can I get plugin.min.js and where should I put it. </p>
  
  <p>My static file configuration in setting.py is </p>
  
  <pre><code>STATIC_ROOT = os.path.join(BASE_DIR,'staticfiles')
  STATIC_URL = '/static/'
  </code></pre>
  
  <p>I am running these in production.</p>
  
  <p>What's the solution? 
  The thing is I want to copy images from word file directly into the RichTextField.</p>
