title: WebPack displaying tslint warning on main page
body: <p>I've been upgrading to webpack 2, but now I cant display main page as I end up with the warning message:</p>
  
  <p>Failed to compile:</p>
  
  <p>./src/app/login/login.component.ts
  [20, 21]: missing whitespace</p>
  
  <p>This is the one of the warning messages that I see in console,
  but it never stopped webpack server from displaying content before.</p>
  
  <p>In Console webpack says: "Compiled with warnings" so there should not be reason for displaying Failed to compile on the main page.</p>
