[WIN32SS] Handle Graphics acceleration level (registry key Acceleration.Level)

Browse source 
- store the acceleration level in PDEVOBJ
- when searching a pdev, search a pdev with required acceleration level
- disable some functions when not at full acceleration level
  (levels 3 and 5 are not implemented)
