Title: Update to Saint Helena and Ascension Island

Saint Helena, Ascension Island and Tristan da Cunha share a combined cca3 code SHN. See also http://www.iso.org/iso/iso_3166-1_newsletter_vi-7_2010-02-22.pdf

So Saint Helena and Ascension Island are not listed separately according to the http://en.wikipedia.org/wiki/ISO_3166-1_alpha-3 list.

If you list them separately they have different ISO 3166-2 codes http://en.wikipedia.org/wiki/ISO_3166-2:SH

SH-AC Ascension
SH-HL Saint Helena
SH-TA Tristan da Cunha

Phone Codes
+290 (Sainte-Hélène)
+247 (Ascension)
+290 8 (Tristan da Cunha)
+27 (Gough Island)
