-------------
- Fixed Cookie path default value to be relative to base site location.
- Added AppendSlashes middleware for forcing URLs to end in slash. Not on as
default.
- Changed handling of requests against invalig URLs (We now process all
requests as if their URLs had a leading slash, regardless...)
- Created ``Responsify`` middleware, and included it as default. This allows
you to return from a route withoute wrapping your response in a Response
object.
- Ensured compatability across Python versions 2.4 through 3.2
