Change sorting in timezones.csv

[StrangeDrVN]

Currently the sorting is done by name. This causes the offset to get jumbled up. The confusion mainly arises while searching for America/Europe.
What if the region/country is sorted alphabetically, followed by sorting by offset? This probably would make searching for the right time zone easier.
I couldn't think of a better way.
