Log message:
Updated to py-HappyDoc-2.1

Changes :

   - #514237 - The PluginLoader no longer requires a '.py'
     extension on plugins.  This should allow plugins to be written
     in any language for which Python can load a module, and as
     long as the file is named with the right convention they will
     be picked up and loaded.  (The source of this change request
     was the maintainers of the PLD Linux Distribution.)
   - Resolved defect #513850, where output was written to the wrong
     place when the -d option was used.
   - Resolved defect #510447, a problem with escaping special
     characters in HTML output.  Text enclosed in single quotes
     is now not escaped in output so that HTML text can be
     passed directly to the output file.
   - Fixed a problem with Windows installation using 'setup.py'.
   - Minor tweaks to the build and test tools.

Log message:
Strip the ".buildlink" from the names of the python application and
extension Makefile fragments, because they really don't have anything to
do with the buildlink[12] frameworks.  Change all the Makefiles that use
application.buildlink.mk and extension.buildlink.mk to use application.mk
and extension.mk instead.

Fix NetBSD tag.
