Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this).  Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right.  Apologies if they're
not.  This also touches the weakref docs, which contains a sample type
object initializer.  It also touches the mmap test output, because the
mmap type's repr is included in that output.  It touches object.h to
put the correct description in a comment.
