FAQ addition

Please add this to the FAQ:

I can launch OpenMW and music plays, but I only see a black screen!

This can occur when you did not import the Morrowind.ini file when the launcher asked for it.
To fix it, you need to delete the launcher.cfg file from your configuration path (https://wiki.openmw.org/index.php?title=Paths), then start the launcher, select your Morrowind installation, and when the launcher asks whether the Morrowind.ini file should be imported, make sure to select Yes.
