Update requirements, Python 3.5 error with naked raise

[adamn]

raise with no arguments can only be used in an except clause as of Python 3.5.

While I was in there, updated some outdated packaging/testing packages

Not clear on first sight why the linting failed in the build.

[adamn]

The linting failed with 405 (but not on my machine oddly).

http://flake8.readthedocs.io/en/latest/user/error-codes.html

The new flake8 is ignoring the #noqa:

from rest_framework.fields import *  # NOQA # isort:skip
from rest_framework.relations import *  # NOQA # isort:skip

It looks like they want you to put #noqa on all the uses now, not the import:

Okay, so I guess that'll either need the noqa addressing, or else just isolate this particular PR to the raise exc only.

[adamn]

I think we should # noqa the whole file with a todo to do the explicit import or # noqa all those lines. It's good to have the benefits of the new linter everywhere else.

[adamn]

Give me a few minutes - I'll just make the linter pass. Just a bit of grunt work.

[EDIT] Give me till tomorrow ... this will require a bit of work

naked raise now resolved in e3686ac

Welcome to resubmit this with just the package updates / noqa fix 😄
