This is mostly just a PoC to see if our CI infrastructure is able to run
cypress.io tests.
Changing language currently triggers a "500 Parse Error" in cypress,

application name. This makes it simpler to change everything to a proper
name when cloning this project.
Document in the README how to find the remaining places to change.
Closes#20
