Template documentation

Anguilla and Angola both use ANG, but since Anguilla is only called via the Commonwealth Games it has been designated ANG_CGF in the Module (and will only be called when "Commonwealth Games" is passed to {{{games}}}).

Hong Kong is no longer a part of the Commonwealth, and to avoid their current flag showing on Commonwealth-related issues HKG_CGF is implemented to avoid their post-colonial flag.

Since these are more back-end fixes they're listed here instead of the /doc.
