[Nitro] request parameters

[Tim Larson]

Periods '.' in request parameter names are handled specially
by nitro, such that you cannot retrieve the value of a param
named 'cats.and.dogs' via request['cats.and.dogs'] but instead
you must use request['cats.and']['dogs'] (hope I got that right.)
This might be really handy in some situations, but I would
really like to also be able to retrieve via the full param name.
