Major release v1.2

This is considered a major release due to a key name change in the JSON objects; therefore making it incompatible with prior db-schema-spec versions.

Release summary

• The key "system-type" has changed to "system" in the schema.json and version.json objects
• Introducing utilities that implement the db-schema-spec specification
  • bin/util/migrate-mysql.sh - migrate a mysql database
  • bin/util/migrate-mongo.sh - migrate a mongo database

Initial release

You might think it should start with v1.0.X, but... there was a prior specification not released. Enjoy.
