feat(db): Add database migration support, implements #19

Migrations allow us to keep track of database changes and upgrading databases if needed.

* Add initial migrations for core Flaschengeist
* Add migrations to balance
* Add migrations to pricelist

* Skip plugins with not satisfied dependencies.
