Format whole project

[tentamens]

After all pull requests are closed I want to finalize on how we want the formatting to look and than format all the files in the project so pull request aren't just a bunch of formatted code

This is the official vue extension that provides the formatting out of the box:

We might have to disable the styling check for eslint though

Me and Flou decided on stylistic formatting from eslint, I am just waiting till there is no new feature or bug being made or fixed to format the project so there isn't unnecessary conflicts
