Make .gitignore more readable

[bittner]

As a developer
I want to have a concise, readable .gitignore file,
which is tailored to the specific framework and technology
So that it's easy for me (and my colleagues) to quickly grasp which files are being ignored
and what I have to add myself (in non-standard projects).

Motivation

The current version of .gitignore for Django and Flask is big and ugly. It's similar to GitHub's gitignore for Python, which contains just about everything you would want to ignore for any generic Python project (PyData, NumPy, SciPy, and IDEs included).

Role Models & Considerations

• Plone .gitignore (GitHub)
• Symfony .gitignore (this repository)

Global gitignore

For IDEs and other stuff that is globally valid on a developer machine we may suggest using an appropriate global gitignore file.
