Listing all programs + sorting + news + linting

Due to sr's API results were paginated by default, hence only showing 10
programs at a time. Now it lists everything, and the results are also
sorted by name.

I also added a news-section.

I have tried to follow [PEP8](http://legacy.python.org/dev/peps/pep-0008/) as far as i could.

I'm a python beginner, so I'm really excited about this project, and hope to learn a lot!
