Improve implementation with better underlying data structure
...
for O(1) deletions. Big-Oh performance now the same as regular
dictionaries. Uses a doubly-linked list instead of a list/seq
to track insertion order.

* The 'del' statement no longer raises KeyError for missing values.
* Add multiset operations: __add__, __sub__, __and__, __or__.

Simplify Counter() API. Replace items keyword argument
...
with a mapping. Makes Counter() idempotent, makes update()
API the same as Counter.__init__(), makes a more readable
repr, makes the API more dict-like, and allows Steven
Bethard's update() example to work.

Minor fix-ups to named tuples:
...
* Make the _replace() method respect subclassing.
* Using property() to make _fields read-only wasn't a good idea.
It caused len(Point._fields) to fail.
* Add note to _cast() about length checking and alternative with the star-operator.
