[en] Update GB speller - 20190901

@Yakov

Hello!

Could you update the British speller?:

For over a month that there is activity in Kevin Atkinson’s GitHub, but so far he hasn’t updated AU+CA+US.

I am not sure when Kevin will update his other spellers… the only thing we have as granted is the GB one.

I will do it tomorrow.

Thank you, Yakov!

I renamed the topic subject since I was thinking about Portuguese and typed in it “[pt]” instead of “[en]”.

Hi Marco,
I updated the en_GB dictionary:

Thank you, Yakov!

Kind regards,
