* Honor parameters order when parsing query and form parameters When parsing the query or form parameters in Request, the values are stored in a MultiMap. This class extends HashMap which does not preserve the order of insertion so a request with parameters "first=1&second=2" might end up in a map where "second" will come first when iterating on the entry set. The order is necessary in some case where the request is signed off the body and/or the query parameters. When the order is not preserved, it is impossible to reconstruct the original request sent, unless using the Request::getInputStream which consumes the stream and makes subsequent calls to Request::getParameters to don't return the form parameters which can be misleading. The same behavior applied to query parameters, by using Request::getQueryString, you get the correct order but Request::getParameters will not. Moreoever, if the application is behind a reverse proxy using Jetty that is proxying using Request::getParameters which consume the request InputStream, it will be completely impossible to reconstruct the original request. * Added a test with parameter merging

I think this import shouldn't be needed anymore.
