activity, capabilities, chat history and the locale picker (21 -> 2)

The locale picker's labels are now AUTONYMS computed from Intl -- each language named
in its own language, so "Português europeu" reads as Portuguese whichever locale the
UI is in. That is the convention for a language picker and the useful behaviour:
somebody who cannot read the current language still has to find theirs.

CapabilityPage interpolated the capability KIND into six strings by lowercasing it in
code. "skill" does not lowercase into a Portuguese noun, so kind is a parameter now.

What is left is two strings, both deliberate: see the next commit message.
