Parses a variety of ``Accept-*`` headers.
These headers generally take the form of::
value1; q=0.5, value2; q=0
Where the ``q`` parameter is optional. In theory other parameters
exists, but this ignores them.

Parses an ``Accept-*`` style header.
A list of ``[(value, quality), ...]`` is returned. ``quality``
will be 1 if it was not given.

This object should not be modified. To add items you can use
``accept_obj + 'accept_thing'`` to get a new object

else matches; or if you include None at the end of the match

Returns the best match in the sequence of matches.
The sequence can be a simple sequence, or you can have
``(match, server_quality)`` items in the sequence. If you
have these tuples then the client quality is multiplied by the
server_quality to get a total.
default_match (default None) is returned if there is no intersection.
