Version 0.0.8

Contains a few optimizations and features added by @felixbuenemann.

Notably:

1. request.get_header('name', default=None)
2. Better caching of request object fields, such as data and cookies.
3. Many more supported HTTP statuses.

Also includes the ability to parse QUERY_STRING in requests.

Example:

• self.request.args - Dictionary of parameters.
• self.request.json_args - A json object passed via QUERY_STRING inside json=.
