Log Message:
Update lang/py34-html-docs to py34-html-docs-3.4.6

pkgsrc changes:
 - Switch MASTER_SITES to https://www.python.org/ftp/python/doc/${VERS}/
   Unlike previous MASTER_SITES the documentation there is not regenerated
   periodically (so it will avoid possible changes in the distfiles).

Changes:
Unfortunately no changelog is available. However, the documentation
is now synced with the lang/python34 version available in pkgsrc.
