- Used the new explosion handling to clean up the old style projectile

definitions. The SimpleProjectile class is gone and it uses the meta
  data and A_ExplodeParms instead now.
- Removed the deprecation warnings for explosion parameters again because 
  the new system is fully inheritable and therefore useful.
- Changed the explosion properties into meta data and adjusted A_ExplodeParams
  to use these when called without any parameters. Also removed all special
  parsing for A_Explode so now this function can be called with expressions
  like any other function.
- Changed DECORATE parsing so that functions with completely optional 
  parameter lists don't create an empty list when called without parameters.
