Python API documentation generation tool Code

- Fixed `ValueDoc.is_detailed()` when there are details in the variable,
but not in the value.

- __revision__ is allowed as variable for the 'version' tag.

- Dropped double anchors definitions.

- Added --include-log to several targets in the Makefile

- Added redirect page <redirect.html> that redirects dotted names to
corresponding pages using javascript. When the user visits
<redirect.html#dotted.name>, they will automatically get redirected
to the page for the object with the given fully-qualified dotted
name. E.g., for epydoc, <redirect.html#epydoc.apidoc.UNKNOWN>
redirects the user to <epydoc.apidoc-module.html#UNKNOWN>.

- Don't barf with non-ascii chars in reST doctest blocks.
Thanks to Nicola Larosa and David Mugnai for pointing this bug.

- Test cases for zope2 and zope3 introspection support

- Fixed various test bugs; updated tests so now they run cleanly under
Python 2.3 (assuming you're using a recent version of doctest.py)

- Added preliminary support for zope2 and zope3 introspection.

- Fixed SF bug #1659520 (although I'm not entirely happy with the fix)
