Final Spanish corrections

In my opinion with this commit we can close the issue #533. I edited `es.txt` and `es-help.txt` in `share/translations`. `we-lang.go` was okay, so I didn't touch it.

I apologize for being absent the last 2 months after suggesting said issue.

Spanish translation corrections and additions

for 2 options not include in es-help.txt but present in help.txt

THIS WILL INVALIDATE THE EXISTING CACHE!
The new cache now pulls data from all three of geoip, ip2location, and
ipinfo, and stores it in the relatively simple city;region;country
format.

The old format would either store city;country or store
countrycode;country;region;city directly from ip2location, so it is much
more consistent with this change.

This comes with something of a refactor.

- IP2LOCATION_KEY is now checked with `if not` to reduce indention
- ConnectionError is increased to RequestException to catch all requests
  errors
  - On that note, now raising for status too
