meetingology should start supporting Python 3

[Aminda Suomalainen]

Meetingology (the bot at freenode) has been running on Limnoria for a long time as it's the only active Supybot fork.

Recently they have been starting to move to supporting only Python 3 which has less issues e.g. with charsets. Meetingology the bot could be converted to Python 3 if the meetingology plugin supported it.

```

Says the most recent meetingology update so I am raising the importance for this issue.

Except that I apparently cannot change importance even if I can mark the issue as confirmed.

Downgrading to older version for now.

[Aminda Suomalainen (mikaela)]

The previous comment was regression in Limnoria that has since been fixed.

* https://github.com/ProgVal/Limnoria/issues/1217

However they still consider this version of Python deprecated, so this issue is important.

[Aminda Suomalainen (mikaela)]

It appears there is no suggestion in Python3 in setup.py anymore, but there is warning about old Python 2.

```
setup.py:247: DeprecationWarning: Running Limnoria on Python older than 2.7.9 is not recommended because it does not support SSL certificate verification. For more informations, see: <http://doc.supybot.aperio.fr/en/latest/use/security.html#ssl-python-versions>
