Add anp

See: https://sourceware.org/bugzilla/show_bug.cgi?id=16078

Also add translations for “India” and “Nepal” in anp and mai:

<rajesh> Both use same script and so the translation will be same for both
<rajesh> India : भारत
<rajesh> Nepal: नेपाल
More testcases for TW and HK
Do not fail if a timezone id part cannot be found in the database

Return the timezone id part untranslated in that case.
