Reduce the inconsistent use of "language" vs. "lingo"

Now we’re just using the word “lingo” for the macro defined in
PageTemplate (where the abbreviation is useful), and using the full
word “language” everywhere else.

It’s possible that we should be using “locale” instead of “language”,
what do you think?
