Show information for music videos when full screen info shown.

Extends point 1. in https://github.com/BigNoid/Aeon-Nox/issues/616 to show more information when playing music videos and concerts.

Changes Music Video playback information from the uninformative:-

To one which has similar information you'd get on Episodes or Films.

The Plot/Cast buttons are hidden as Cast appears to always be un-populated. Studio logo behaviour is now cloning that when viewing "information" on episodes (e.g. display text when no image) - e.g. Epic Amsterdam here.

Also works well with DVD sized artwork.

I've done that to copy the behaviour from the full screen info in movies - i.e. rather than displaying the "?" it displays the studio name as text - it's seems a tad inconsistent in what the fall back position is as most views it's the "?" but the detail shows something useful

E.g. when viewing movie info from the library you get the following:-

yet the OSD shows like the following :-

This change instead shows the label instead :-

and for movies :-

Guessing this is more of a personal preference as to weather or not the ? or text is more visually pleasing.
