Java Client: Headers and form data

The Java client as of 1.2.6 does not support http headers and form data. I patched the library, adding the following to RaygunRequestMessage. Feel free to use.

      headers = new LinkedHashMap<String, String>();
      {
          Enumeration<?> e = request.getHeaderNames();
          while (e.hasMoreElements())
          {
              String name = (String)e.nextElement();
              String value = request.getHeader(name).toString();
              headers.put(name, value);
          };
      }
      form = new LinkedHashMap<String, String>();
      {
          Enumeration<?> e = request.getParameterNames();
          while (e.hasMoreElements())
          {
              String name = (String)e.nextElement();
              String[] values = request.getParameterValues(name);
              form.put(name, concat(values, ";"));
          }
    }
