We need to enable auto close in github pull requests

Looking at https://github.com/pulls?q=is%3Apr+org%3Akde+is%3Aopen makes me  
very sad seeing how there's people that want to contribute but will never get 
an answer.

Even if you click to those 109 closed you can see how there are some that are 
from people that clearly got fed up from waiting.

Please people that administer the github account (¿Riddell?) make that happen
