some tests, and removing regex in jsni generator

Julien the only important thing in this request is the replacement of regex by a parser in JSNI generator, because I found many errors when importing compressed libraries and complex js sentences.

Also we can import remote libraries

Now, this sentence works like a charm

`
public interface HighCharts extends JsniBundle {
  @LibrarySource("http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js")
  public void initJQuery();
  
  @LibrarySource("highcharts.src.js")
  public void initHighcharts();
}
