[Tagging] destination:symbol tag: country-specific symbols

[Jez Nicholson]

Whilst we are on country-specific symbols perhaps the use of
non-country-specific references such as 'ref:nrhp' and 'ref:nhl' could be
reconsidered, i.e. use 'ref:US:nhrp' and 'ref:US:nhl'. The
country-specificness would then be more obvious, and potential clashes with
other countries could be avoided.

It may be too late for NHRP as there are 6,500, but NHL has just 26
currently.
