title: Javascript analysis fail for .js files containing ES7 Decorators
body: <p>I'm currently using Babel (the Javascript transpiler) which allows me to use the future syntax now. I'm using the decorator functionality (<a href="https://github.com/wycats/javascript-decorators" rel="nofollow">https://github.com/wycats/javascript-decorators</a>). However when I run analysis on that code, SonarQube throws the following error:</p>
  
  <p>[09:19:43] 09:19:43.693 ERROR - Unable to parse file: /...../my-form.js
  09:19:43.693 ERROR - Parse error at line 10 column 1:</p>
  
  <pre><code>1: import {View, Component, Inject, NgScope} from 'app/app';
  ...
  9: 
  10: @Component({
      ^
  11:   selector: 'my-form'
  12: })
  13: @View({
  14:   template: myTemplate
  15: })
  </code></pre>
  
  <p>Will this be covered soon by the Javascript plugin (or at least skipped by the parser but allowing it to continue processing of the file)?.
  Is there a way to file a JIRA issue for this?</p>
