[PATCH] traditional post-release doc text and release-check.sh updates

[Tomi Ollila <tomi.ollila@iki.fi>]

- added period to the end of the only 0.20.1 news item so that news2wiki
  will not make it a header line

- changed copyright year to 2015 in doc/conf.py

- made release-checks.sh to check copyright year in doc/conf.py

- made release-check.sh to execute python3 compatible version check code
