Title: Tidy up gateway lists

Hope this seems reasonable. When looking for supported gateways in the UK, I was initially tripped up that some were 'GB' and some 'UK'. Also, they're in a slightly funny order.

Put gateway lists in alphabetical order.
(Ignoring punctuation and case; shorter-first.)

Pick a consistent country code for the UK; I don't think this doc
cares about the fine distinctions between UK of GB & NI and GB.
