Missing translation strings

Issue type: Feature request

Actual behaviour

There are missing translation strings in both Ultrastar Play (and, of course, Melody Mania) and the Companion App. To show them I've attached screenshots of the game set to Spanish so the non-translated ones are visible in English

Thank you for testing this and the detailed bug report.
This is easy to fix, but not a prio at the moment.

Further, I think the technical terms "Version", "Commit", "UNity version", "Build timestamp" are ok to stay English.
