Make video metadata strings translatable in frontend
In the video page, a small part of the strings was untranslatable, e.g. “Player: ”.
These were part of the video metadata. Now these are localizable.
Directory for automated tests to test the engine.
Run `ctest` in the root directory of this repository to run all tests.
Run `ctest -R <test name>` to run only the test with the given name.
This requires you to have CMake.
