This patch also does away with an incompatibility between Jython
and CPython.

test_formatdate_zoneoffsets() => test_formatdate_localtime(): Do the
sign corrected calculation of the zone offset.

negative modulus won't return the right values.  So always do positive
modulus on an absolute value and twiddle the sign as appropriate after
the fact.

use the correct way to test for epoch, by looking at the year
component of gmtime(0).  Add clause for Unix epoch and Mac epoch (Tim,
what is Windows epoch?).

Also, get rid of the strptime() test, it was way too problematic given
that strptime() is missing on many platforms and issues with locales.
Instead, simply test that formatdate() gets the numeric timezone
calculation correct for the altzone and timezone.

incorrect for "uneven" timezones.  This algorithm should work for even
timezones (e.g. America/New_York) and uneven timezones (e.g.
Australia/Adelaide and America/St_Johns).

Fixed a couple of minor markup issues as well.

urlsplit() and urlunsplit(), that do the simpler job of splitting the URL

This closes bug #478038.

Cleaned up some markup nits.
Add a few more of the Tk-related modules to the list of modules.

Fred, please proofread!

find_class(): We no longer mask all exceptions[1] by transforming them
into SystemError.  The latter is definitely not the right thing to do,
so we let any exceptions that occur in the PyObject_GetAttr() call to
simply propagate up if they occur.

[1] Note that pickle only masked ImportError, KeyError, and
AttributeError, but cPickle masked all exceptions.

load_inst(): Implement the security hook that cPickle already had.
When unpickling callables which are not classes, we look to see if the
object has an attribute __safe_for_unpickling__.  If this exists and
has a true value, then we can call it to create the unpickled object.
Otherwise we raise an UnpicklingError.

find_class(): We no longer mask ImportError, KeyError, and
AttributeError by transforming them into SystemError.  The latter is
definitely not the right thing to do, so we let the former three
exceptions simply propagate up if they occur, i.e. we remove the
try/except!
