Updates the en county list to be a lomger list of US-esque county names instead of a
truncated list of GB county names.

Shouldn't we mix other states counties in as well otherwise en == en_US.
Maybe lets discuss this in the next team meeting.

[matthewmayer]

We don't do that for state()

[ST-DDT]

There seems to be merge conflicts. Could you please fix them?

[ST-DDT]

Team decision

We will use both the "British" and US county names for en.

[matthewmayer]

Done.

Note this is a good example of why you don't always want to sort definitions alphabetically re #2265
