title: Warning that 'imported libraries have the same name when they DO NOT"
body: <p>I have the following import statements in a class</p>
  
  <pre class="lang-dart prettyprint-override"><code>import 'package:dart_web_toolkit/ui.dart';
  
  import '../../util/flex_table_builder.dart' as ftBldr;
  
  import '../factors_list_view.dart';
  
  
  class MediatingFactorsView extends Composite
  {
   //... 
  }
  </code></pre>
  
  <p>However, the last import statment is flagged with a warning: </p>
  
  <pre><code>The different imported libraries 'flex_table_builder.dart' and 'factors_list_view.dart' should not have the same name
  </code></pre>
  
  <p>The names are quite different and I see this being repeated throughout my code after I updated to the latest Dart Editor. Is this a bug?</p>
