Description

Hi team -
I took the en_us file and checked for entries that were not defined in the es_es file. I added those and added their spanish translations. I've also updated some of the old ones.

Testing

Required verification:

• I've verified that there are no regressions in mvn test (there are no new failures or errors).
• I've verified that this change works as intended.
  • Downloads all relevant content.
  • Downloads content from multiple pages (as necessary or appropriate).
  • Saves content at reasonable file names (e.g. page titles or content IDs) to help easily browse downloaded content.
• I've verified that this change did not break existing functionality (especially in the Ripper I modified).

Optional but recommended:

• I've added a unit test to cover my change.
