Language subtag registration for 1990aolp

[João Miguel Neves]

First of all, thank you all for the feedback. I learned a lot more than
I was expecting, which is great.

This is the first of two emails (one for 1990aolp and one for 1945colb).
I also have a template prepared for 1911buo, but I'll wait until
something closer to a consensus is reached on its need (Francisco,
António: I've sent you the template directly, feel free to submit to the
list whenever you feel it makes sense). Changes from previous submissions:

 * Variant tag name changes as a result of the discussion.
 * The acor1971 was replaced by 1945colb (as I learned the difference of
a major language reform).
 * References where provided by Francisco and António.

Francisco, António - I didn't credit you on the 1990aolp submission
given your opposition to the references used. If I assumed too much just
say and I will gladly change that.

So here's the (hopefully final) proposal:
