Added code to allow for time zone name substitution in the app.

Disabled search by time zone
Sort by actual offset (respects DST) then country, then name
Dropped TZs without country. They are usually dups and since we don't search by tz name, they are hard to find.
Move Sydney above Hobart, Australia
Moved Adelaide above Broken Hill, Australia
Moved Dawson_Creek above Creston, Canada
Updated string descriptions
