Backend: english terms

[marcosmenendez]

Many terms are incorrect or not aligned with url and database names. Some url in capital letters as well.

There are terms that are called in multiple ways depending on the menu (for instance announcements and achievements)

I suggest you build an excel with the list of database fields, backend url's and names shown in the menu to identify inconsistencies and then decide how to change them.

Requires thorough revision. It is a cosmetic issue, but it looks bad in case we show the backend to external people.
