Fix SF #642742, property() builtin not documented

Added doc for functions new to 2.2:  classmethod property staticmethod super
Taken from docstrings.  Could use review.
Hope there wasn't a reason why these shouldn't have been added.

Backport candidate.

+  A static method does not receive an implicit first argument.

+\begin{verbatim}
+class C:
