title: suppress for fields annotation
body: <p>I'm using <a href="https://github.com/JakeWharton/butterknife" rel="nofollow">butterknife </a>library to my project to use Bind annotation instead of findViewById.</p>
  
  <p>when I use <code>@Bind(R.id.button) Button mButton;</code> 
  but never use it, android studio show me warning that I never used it and highlight it with yellow. </p>
  
  <p>when I press Alt+Enter for quick fix -just exploring- and choose the secound choise </p>
  
  <blockquote>
    <p>suppress for feilds annotated by 'butterkife.Bind'</p>
  </blockquote>
  
  <p>the warning is gone, but then when I tried to undo what I have done it does't work what ever I tried.</p>
  
  <p>I know it's small thing but it's really annoing.</p>
