according to the MS docs it enables exception-handling, and (according
to Alex Martelli <aleaxit@yahoo.com>) is needed to compile without
getting warnings from standard C++ library headers.  Apparently
it doesn't cause any problems with C code, so I haven't bothered
conditionalizing the use of /GX.

* deletes cache
* adds firstweekday and setfirstweekday functions that allow user to control
  which day of the week is first when displaying calendars
* adds month, week, calendar functions that return their results instead of
  printing them
* adds symbolic constants MONDAY, ..., SUNDAY so users need not remember the
  ordinal values of the weekdays

Simplify some of the path-math since we can assume a recent version of

of extended print.  If the file object being printed to is None, then
sys.stdout is used.

Changed 'core.setup()' so it sets them to reasonable defaults.
Tweaked how the "usage" string is generated: 'core' now provides
  'gen_usage()', which is used instead of 'USAGE'.
Modified "build_py" and "sdist" commands to refer to
  'self.distribution.script_name' rather than 'sys.argv[0]'.

this addresses (but doesn't really solve) bug #112693, and low-memory
problems reported by jack jansen.

Fix bad operator precedence: should be "(metadata or '') + '\n'".

how 'import' was called with a compiletime mechanism: create either a tuple
of the import arguments, or None (in the case of a normal import), add it to
the code-block constants, and load it onto the stack before calling
IMPORT_NAME.
