Spanish translation

[hagenburger]

Thanks to @catalanojuan, this is already started: https://docs.google.com/document/d/1v2vBT7VhSaV0cINWj-EdpuMe5X7fE7LeaJffWdU60rc/edit?usp=sharing

We should turn it into a pull request to discuss details over there.

@hagenburger thanks for opening the issue! I opened the gdoc so that everyone with the link can access and changed permission so everyone can view & comment. I've commented there some parts I'm still doubtful about.

I've also opened PR #23 to work on this and discuss the details.

Hey Juan! I added my input on some minor elements in phrasing and followed your comments. I hope it helps!

I’m closing this as the Spanish translation is online. Yay :)

If anybody has further comments, just open a new issue or pull request.
