Merge schema upgrade files for v0.2.0

This gives a single file that can be applied during the upgrade more easily,
having it in individual files was mostly to avoid merge conflicts during
development.

The combined files were created with the following command:

  cat 0.2.0-external-uuid.sql <(echo) 0.2.0-source-rules.sql <(echo) 0.2.0-schedule-timezone.sql <(echo) 0.2.0-source-username.sql > 0.2.0.sql

The order of files matches the order in which the PRs that added them were
merged (though the order shouldn't really matter as there are no dependencies
between the individual files):

 - #216
 - #324
 - #344
 - #338
