* remove duplicated fields
* make native functions use direct calls
* remove unnecessary pointer from particle_t
* create HWSprite directly in Construct
- Effectively similar to Actors, but without the excess.
- Can be created with either the `level` function or the static `Spawn` function in ZSprite.
- STAT_SPRITE belongs to ZSprites only; ZSprites cannot be moved out of, nor can anything else be moved in to, this statnum.
Misc:
- Fixed (Sprite)Offset taking roll into account.
Crediting phantombeta, RicardoLuis0 and RaveYard for assistance.
Due to C++ conversion rules this was a bit too volatile. There's really not enough places where being able to pass a string directly into the sound API was beneficial - the two most frequent functions now got overloaded variants.
- added Marisa Kirisame's CHAN_OVERLAP flag.
- exported S_IsActorPlayingSomething to ZScript.
The sound API change required deprecating A_PlaySound and S_Sound. There are now new variants S_StartSound and A_StartSound which have two distinct parameters for channel and flags.
This was only run on a state change and missed every external light change.
Any place which wants to flag a light change now only will set a flag and at the end of the thinker loop all flagged actors will be processed.
For performance reasons this was merged with the P_RunEffects iterator loop.
