this breaks stuff with hibernate 5.2
(though somehow didn't when I first tested it?!)

7 tones used according to https://www.ibm.com/blogs/watson/2017/07/ibm-expands-watson-tone-sensitivity-for-customer-service/

the latest release spring-starter-data-jpa uses an older hibernate version (5.0.12) that does not support java8 features like time and date.

we use this to override it with our own dependency as long as spring-boot uses the old one.

just an idea in the maybe right direction
not necessary for our prototype as we probably won't work globally

does things automatically for us without having to explicitly state it - might do stuff we have no clue about.
But its a prototype - so what could possibly go wrong?

as long as we don't use authentication (with eg. spring-security) we won't need a session for REST services.

- rename and restructure our only model object
- repository may be able to handle REST stuff alone

## remove flyway for now.

hibernate can automatically update the scheme.
Should be enough for our small project.

## add spring data-jpa.

a bit more important for working with a database

Some dependencies are interesting for way later.
So we can remove them for now to have a more neat pom.

already removed some stuff - did not look _that_ important.
