method that ignores missing keys:
\begin{verbatim}
->>> t = string.SafeTemplate('$page: $title')
+>>> t = string.Template('$page: $title')
>>> t.safe_substitute({'page':3})
u'3: $title'
\end{verbatim}
\item Strings also gained an \method{rsplit()} method that
works like the \method{split()} method but splits from the end of
the string.
