[feature/new-tz-handling] Update tz_select() to use the PHP timezone database.

Browse Source 
tz_select() now uses the PHP timezone database to generate the timezone
selection box, it tries to use a translated language string otherwise falls
back to a label produced from the timezone identifier. I've done this so
new timezones are available immediately without a new language pack.
