Failure on Python 3.4 / drop support?

[magical]

I'm seeing a new build failure on Python 3.4.

https://travis-ci.org/github/veekun/pokedex/jobs/765569618#L241

File "/home/travis/virtualenv/python3.4.8/lib/python3.4/site-packages/sqlalchemy/util/compat.py", line 189, in

from typing import TYPE_CHECKING

ImportError: No module named 'typing'

Looks like a recently introduced incompatibility in sqlalchemy. I could investigate further, but I'm inclined to just drop Python 3.4 from the test matrix since it is past its expiration date.

Any objections?

For what is worth, this should be fixed in the next sqlalchemy 1.3.x patch release: sqlalchemy/sqlalchemy#6168
