Rocket 1.2.2

The focus of this release was easy speedups. Some changes are:
- ChunkedReader doesn't cache anymore (this is actually faster and uses less memory)
- new-style classes and slots (where appropriate) are used to reduce memory consumption
- the request line is parsed with a regexp on all platforms except Jython for a little more speed while validating better.
- tests just keep getting more comprehensive.
