[Freelenzer]

This add first implementation of region/continents

i will add a PR for Subregions later.

What else needs to be done here?

What can we add to regions? Timezones?

@Freelenzer Thank you for your hard work on this! I really appreciate it.

Can we please keep the region and subregion columns as is so they stay backwards compatible?

Also, can you please migrate the updates of the regions, subregions table and countries table within world.sql?

The JSON, CSV, XML & YAML formats will get autogenerated once this PR is merged. You don't have to worry about them.
