Remove middleware: connect.bodyParser()

Because `connect.bodyParser() is deprecated and
will be removed in Connect 3, this commit removes
it from the middleware stack and replaces it
with `connect.urlencoded()` and `connect.json()`.

See https://github.com/senchalabs/connect/wiki/Connect-3.0
for more information.
