added new screen definition for global animations in the hall of fame

This adds a new screen suffix ".SCORESONLY" for global animations,
which can be used to display animations only on the main screen of
the hall of fame, but not on the score details page (which can be
defined using ".SCOREINFO"), while using ".SCORES" shows animations
on both the main scores screen and the score details pages, as before.
