Semi-Merge achievements branch, regenerating the schema changes with newer migrations, which hopefully does not break the schema again :(
- Update CRUD for achievements
- Add first simple AttributeValidator which will now be tested ;)
- Create migrations to remove some "necessary" model attributes (we should review next Tuesday of what stuff we can get rid off...)
Add seeds holding the data our app must seed when deploying... do not run this multiple times or you will get duplicated data ;)
I will probably add this stuff in a migration, although it's not recommended
