Fix time.strptime's %U support. Basically rewrote the algorithm to be more
generic so that one only has to shift certain values based on whether the week
was specified to start on Monday or Sunday. Cut out a lot of edge case code
compared to the previous version. Also broke algorithm out into its own
function (that is private to the module).
