  Monkey patch webob Request object

Sadly, a monkey-patch on the webob request object is needed because of the way
it messes with the WSGI environ.

The sympton was that Werkzeug was crashing when trying to access
`request.form` from the new Flask-based API view (this is Flask request
object). Werkzeug was throwing a ValueError when trying to parse the
WSGI environ CONTENT_TYPE value, which was `; charset="utf-8"`.

This has been going on forever (just check any stack trace from Pylons
locally or on a production site) but up until now apparently nobody needed
to use it properly.

The first option was of course trying to upgrade WebOb to see if that
fix the issues. Sadly upgrading WebOb means upgrading Pylons as well,
and that proved too much of a task.

This patch adds a small monkey patch for the
webob.request.BaseRequest._charset__set function, which essentially
wraps the original function and check the value of
environ['CONTENT_TYPE'] at the end. If it is the wrong value starting
with `;`, it sets an empty value.
