Subject: Fix travis CI builds (py2.7 and py3.5); update TODO

This took some epic Travis/Julia/Python munging because of Travis's
weird python path setup, and it will probably break as soon as python
is upgraded from 3.5 to 3.6 on their servers.

Might be useful to other Julia Python-wrapping libraries!
