- fix download url

- update to 1.6.1:
- Response.from_file now parses the status line correctly when the status line
contains an HTTP with version, as well as a status text that contains
multiple white spaces (e.g 404 Not Found). See
https://github.com/Pylons/webob/issues/250
- Python 3.2 is no longer supported by WebOb
- Request.decode attempted to read from the an already consumed stream, it has
now been redirected to another stream to read from. See
https://github.com/Pylons/webob/pull/183
- The application/json media type does not allow for a charset as discovery of
the encoding is done at the JSON layer. Upon initialization of a Response
WebOb will no longer add a charset if the content-type is set to JSON. See
https://github.com/Pylons/webob/pull/197 and
https://github.com/Pylons/pyramid/issues/1611
- Lazily HTML escapes environment keys in HTTP Exceptions so that those keys in
the environ that are not used in the output of the page don't raise an
exception due to inability to be properly escaped. See
https://github.com/Pylons/webob/pull/139
- MIMEAccept now accepts comparisons against wildcards, this allows one to
match on just the media type or sub-type, without having to explicitly match
on both the media type and sub-type at the same time. See
https://github.com/Pylons/webob/pull/185
- Add the ability to return a JSON body from an exception. Using the Accept
information in the request, the exceptions will now automatically return a
JSON version of the exception instead of just HTML or text. See
https://github.com/Pylons/webob/pull/230 and
https://github.com/Pylons/webob/issues/209
- exc._HTTPMove and any subclasses will now raise a ValueError if the location
