[WIP] Add flake8 and vim configs

[rfleschenberg]

• Add flake8 config file
• Test it
• Add a flake8 check to travis
• Fix all current flake8 errors

If we add a .flake8 file, shouldn't we also add --flake8 to addopts in pytest.ini?

[rfleschenberg]

That would be a possibility. I usually have a flake8 check as a separate step in CI, so that CI can fail early if there are flake8 problems. But I never used py.test with --flake, maybe I should take a look at that.

[rfleschenberg]

After a quick look at https://pypi.python.org/pypi/pytest-flake8, I wonder what the benefit of this plugin over just running flake8 directly is.

@rfleschenberg can we close this?

[rfleschenberg]

It's ok if you close it, but I'd prefer to keep it open, but as a low-priority, "maybe if I have time" kind of thing :)

About .vimrc:
I'm not very favorable adding IDE/Editor specific stuff to the repository. Each IDE has their own config files and adding all of them can create a mess.
There is one exception to this: .editorconfig which is understood by all major IDEs.

[rfleschenberg]

I'd prefer to read these from .editorconfig, unfortunately that's not supported with my current setup. I should probably modernize my Vim setup. Time constraints :(

If you decide to remove the vim config, then you need to remove it
