New colorama release breaks zest.releaser install on Python 3.4.

[JPTeasdale]

Looks like colorama dropped support for Python 3.4 which means that pip install zest.releaser breaks on python 3.4 as well.

$ pyenv global 3.4.10
$ pip install zest.releaser
Collecting zest.releaser
Collecting colorama (from zest.releaser)

colorama requires Python '>=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*, !=3.4.*' but the running Python is 3.4.10

I guess the simplest solution is to drop support for 3.4 ourselves, too? (Or at least stop advertising that we support it and stop running the tests for it). @mauritsvanrees?

The above error should be fixable by first doing pip install colorama with a version constraint that still works.

I am fine with dropping 3.4 support. I am not using it.

Actually:

• Our .travis.yml does not test it. It tests 2.7, 3.5, 3.6, and pypy.
• Our tox.ini tries to test with 3.3+, but I am not using it, might be outdated (could be useful though).
• Our setup.py claims 2.7 and 3.5+ and PyPy in the classifiers.

So it seems we do not have to do anything (except maybe cleanup tox.ini).

For me personally (and the Plone community in general):

• Python 2.7 support is very much wanted, but I suspect this will get trickier, for example latest setuptools does not support it. So it is understandable if we drop this at some point this year. But preferably not.
• Python 3.6, 3.7, 3.8 support is needed. Earlier versions not.
• PyPy and PyPy3 are nice to have.

I'm closing the issue, we don't support 3.4 anymore :-)
