Add spanish word list

[jawlenskys]

Add a 8192 words-long Spanish wordlist. The wordlist was generated from two different sources of words:

• The file /usr/share/dict/spanish from Debian's wspanish package.
• A list of the most used Spanish words from Corpus de Referencia del Español Actual (CREA).

The final Spanish wordlist has been generated as follows:

* Start from /usr/share/dict/spanish and filter out:
    - words not matching /^[a-z]+$/
    - words shorter than 4 characters
    - words longer than 8 characters
* Do the same with the CREA word list.
* Compare both lists and extract the words that appear in both lists.
* Remove all words that are a suffix of any other word in the list.
* Remove some offending and non-Spanish words.
* Change some of the hard-to-remember words and replace them
  with some easy-to-remember words from CREA's list.

Hey Victor,
Impressive work! Thanks a lot!

Hi @ulif,
I've only just realised that I didn't specify the licence of the word lists I provided (es, ca and it). I'm fine with the CC-BY-3.0.

These three word lists were also provided as part of Tails. Should I create a PR to add this information?

Hi Victor,

Could you also imagine to apply CC BY 4.0 to your lists? It seems to be a bit easier to adapt for licensees (no need anymore to tell the title of a work, for instance) and looks more mature than the previous CC licenses. I will switch at least my own lists to CC BY 4.0. (Differences)

Awesome, that your lists are also part of Tails. This info should be given also in the diceware docs. I love Tails, support it also financially, and try to spread it whenever possible :)

I am planning for a (major) release around chrismas, just waiting for a longer French wordlist from Tango. Therefore I would be happy to incorporate your copyrights (with a remark about Tails) in diceware, but also wouldn't refuse a PR if you have the time :)

Yes, no problem.

That sounds great! Done in #113.
