Obey PEP8

[miili]

Let's make the code conform with PEP8!

https://www.python.org/dev/peps/pep-0008/

The standard notation will make the code better readable.
Please give a short feedback... We (@HerrMuellerluedenscheid, @miili) could start on that.

Hey guys. Thanks for suggesting this!

Here's what I put in CONTRIBUTING.rst:

• Please ensure that your code conforms to PEP-8.
  • You may deviate from PEP-8 if you feel that your changes improve readability, but be aware that you may be asked to justify your decision.

If you'd like to take a firmer stance on PEP-8, I'm fine with that. Maybe we can add flake8 to the Travis CI build, so that PEP-8 compliance becomes part of the acceptance criteria for new pull requests.

Well, since I have some free type and star citizen will not launch this year, I'm open to contribute by inspecting the code and refactor it if necessary.

[HerrMuellerluedenscheid]

I did a quick flake8 (#146). Any comments about the employed style?

[thcp]

So, I did a quick Insect before starting working on this and I noticed some violations. I'm going to pick this up as soon as possible, but you guys should at least consider setting the identation of 4 instead of 2.

I would be hard-pressed to argue against adopting standards in an open-source project (:

The 2.0.4 release will be delayed a bit while I figure out how to update the C extension, so that should give a decent-sized window to get these changes into the next release.

It would also be super cool if we could integrate flake8 into the build process (random example).
