are consistent with the corresponding tuple index.

* Add optional argument to popitem() -- modeled
  after Anthon van der Neut's C version.
* Fix method markup in docs.

Adds tests, switches from list to deque, fixes __reduce__
which was unnecessarily copying __keys.

for Iterator and MutableSet.  Also added thorough test for
required abstractmethods.

* Constructor and update() support keyword args (like their dict counterparts).
* The 'del' statement no longer raises KeyError for missing values.
* Add multiset operations:  __add__, __sub__, __and__, __or__.

Fix namedtuple bug reported by Glenn Linderman.  Template did not form correctly if the field names were input in Unicode.
