[development doc updates]

[Fred L. Drake]

The development version of the documentation has been updated:

    http://python.sourceforge.net/devel-docs/

Updated the httplib docs to cover the API provided in recent versions of
Python.  Please review and comment on this and all other new material!

(In case you have forgetten, other large chunks of new material include the
sections covering modules in the email package, the compiler package, and
the Tkinter/Tix chapter.)
