Added Spanish translation

[corp-0]

Hey! This is my first pull request ever so forgive me if I did something wrong.

I added Spanish translation to stringtable.xml, doing a pull request in this branch because I guess this is the most recent and in development (?).

Let me know if I did wrong so I can get better in this github thing.

Thanks a lot for the Spanish translation.
No need to apologize 😄 people, who want to contribute, are always welcome. 🤗

The PR looks fine to me.

I'll merge once I'm ready to release the new update, although this will probably take a while because I'm waiting for a command to (hopefully) be implemented into the game ^^

I hope that's okay for you 😃

Yeah, what I meant was if it is ok to PR in this branch or should I use master instead. I see most of the people doing PR on master but I guess that's the stable version and thus shouldn't be modified until merged with the branch in development when is done(?)

Sure thing, you're the boss.

Should I close the PR myself?
