App is ready for acceptance

[MiKessels]

In this PR, the app will be updated to the newest version.

Works

• App shows reparations from the postman mock server
• Reparations are clickable
• View to add new reparation is available
• Login is kind of available

Not Working

• Post new reparations
• Edit reparations
• Safe login isn't available, every username checks out
• OAuth

TODO - Make the code cleaner - Proper name convention

• Fix issues
• Add tests

From now on, I will create smaller PR's for better understanding.
