title: React Native Gifted Chat - Video message is not clickable
body: <p>Can any one help me through react native gifted chat? 
  I'm making a full fledged chat app, having all features like text, image, video, document etc. By default I can chat using text and image. Can anyone help me with the code snippet of Video implementation?
  I need to show a video player onPress Video Message.</p>

  <p>There are some custom props which can be used but I'm stuck, would appreciate any help or snippets I can get for running video in chat.</p>
  
  <p>I've tried almost every prop regarding video:
  <br>
  1. <code>renderBubble={this.renderBubble}</code> <br>
  2. <code>renderMessage={this.renderMessage}</code> <br>
  3. <code>renderCustomView={this.renderCustomView}</code></p>
  
  <p>This is the following code which is showing the video (auto plays &amp; then stops, no video button overlay):</p>
  
  <pre><code>this.setState({
  messages: [
  {
  _id: 3,
  video: 'https://www.w3schools.com/html/mov_bbb.mp4',
  createdAt: new Date(),
  user: {
  _id: 2,
  name: 'React Native',
  avatar: 'https://placeimg.com/140/140/any'
  }
  ]
  });
  
  &lt;GiftedChat
  messages={this.state.messages}
  user={{
  _id: userId
  }}
  renderActions={!socialize &amp;&amp; this.renderActions}
  onSend={this.sendMsesage}
  onInputTextChanged={this.onChangeText}
  text={this.state.message}
  /&gt;
  </code></pre>
  
  <p>When I press the video message, the message should open in video player which can be lightbox or react-native-video.</p>
