title: Vaadin widgetset path is changed after updating to 7.7.0
body: <p>In my Vaadin application, I have my own widgetset specified like below in <code>web.xml</code></p>
  
  <pre><code>    &lt;init-param&gt;
          &lt;param-name&gt;widgetset&lt;/param-name&gt;
          &lt;param-value&gt;com.foo.bar.AppWidgetSet&lt;/param-value&gt;
      &lt;/init-param&gt;
  </code></pre>
  
  <p>And, I had placed my <code>AppWidgetSet.gwt.xml</code> file in <code>src/main/java/com/foo/bar/AppWidgetSet.gwt.xml</code></p>
  
  <p>This setup worked fine until I upgraded to vaadin 7.7.0 (from 7.6.8). After upgrade, I got following error, when I try to access the app through a browser.</p>
  
  <pre><code>INFO: Requested resource [/VAADIN/widgetsets/AppWidgetset/AppWidgetset.nocache.js] not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.
  </code></pre>
  
  <p>It seems like vaadin is looking for a different location for the widgetset, so I placed my <code>AppWidgetSet.gwt.xml</code> in the root of the classpath (<code>src/main/java/AppWidgetSet.gwt.xml</code>) and re-built the app.</p>
  
  <p>Then it worked again.</p>
  
  <p>Is specifying the widgetset as an init param no longer available? Do I have to place the widgetset xml in the root of the classpath itself?</p>
