Exceptions thrown in functions have their stack traces discarded

[GoogleCodeExporter]

This makes debugging applications which use custom functions difficult.

If an exception is thrown by

TofuEvalVisitor.java:75 return fn.computeForTofu(args);

The stack trace is not recorded, because the catch clause does:

      throw new RenderException(
          "Error while computing function \"" + fnNode.toSourceString() + "\": " + e.getMessage());

Fixing this alone would not be enough, as later on the RenerException is 
converted to a SoyException thus:

/**
   * Creates an instance by copying a RenderException.
   * @param re The RenderException to copy.
   */
  public SoyTofuException(RenderException re) {
    super(re.getRawMessage());
    this.templateName = re.getTemplateName();
  }
