IMPORTANT NOTE: I uncommented some code depending on the missing x86.cpp file to allow this to compile, These changes must be reverted as soon as this file is added (see v_palette.cpp and win32/i_system.cpp.)

- Removed AT_GAME_SET because it's no longer used anywhere.
- Converted the last remaining global classes to DECORATE.
- Fixed: Inventory.PickupFlash requires an class name as parameter not an
  integer. Some Hexen definitions got it wrong.
- Converted Hexen's Pig to DECORATE.
- Replaced the ActorInfo definitions of all internal inventory classes with 
  DECORATE definitions.
- Added option to specify a powerup's duration in second by using a negative
  number.
