bind_class() and bind_all() are destroyed when the widget to which
they were passed is destroyed.

The attached patch adds the following behavior to the handling
of REDUCE codes:

- A user-defined type may have a __reduce__ method that returns
  a string rather than a tuple, in which case the object is
  saved as a global object with a name given by the string returned
  by reduce.

  This was a feature added to cPickle a long time ago.


- User-defined types can now support unpickling without
  executing a constructor.

  The second value returned from '__reduce__' can now be None,
  rather than an argument tuple.  On unpickling, if the
  second value returned from '__reduce__' during pickling was
  None, then rather than calling the first value returned from
  '__reduce__', directly, the '__basicnew__' method of the
  first value returned from '__reduce__' is called without
  arguments.

I also got rid of a few of Chris' extra ()s, which he used
to make python ifs look like C ifs.

__builtins__ for all calls to eval().  This still allows someone to
write string.atof("[1]*1000000") (which Jim Fulton worries about) but
effectively disables access to system modules and functions.

have been configured, string.atof() should not fail when "import re"
fails (usually because pcre is not there).

This opens up a tiny security hole: *if* an attacker can make "import
re" fail, they can also make string.atof(arbitrary_string) evaluate
the arbitrary string.  Nothing to keep me awake at night...

mode.  The pickler always uses base 10 so the default base should be
fine.  (The base gets us in trouble when there's no strop module, as
the atoi() in string.py only supports base 10.  This is for JPython.)

Untabified and minor tweaks by me.

duplicates, and otherwise at least as good.

This is handy though for things like grail.

ignoring the '#'.

but value isn't, and value should be DECREF'ed.
