- SoundClass is instantiated to "" by default. Since this property is only used when it is not empty (otherwise GetSoundClass just defaults to player), we can get away with this.
- We may want the soundclass to remain the same if we explicitly set it to the same one that is currently used (say, we set SoundClass to "Caleb" so all other skins can use it)
- GetActorProperty for APROP_SoundClass just calls GetSoundClass,
- CheckActorProperty also just runs GetSoundClass
- GetSoundClass is no longer a static method. We needed to access it in other places.
- Made renovations to GetSoundClass. First of all, SoundClass is no longer instantiated there. Secondly, skinned sounds are now returned if SoundClass is empty. Thirdly, "sclass" in this method will return the default soundclass of the player pawn or SoundClass, depending on if SoundClass is empty. Finally, sclass will retrieve "player" if it is empty.
Many of the simple wrappers have been moved to a separate file and the sound source handling has been abstracted.
This is only the first phase, the work is not complete yet.
Also changed the license of the sound code to BSD after verifying that this code bears no similarity to id's original sound code anymore, save for a few function names (which are due to be refactored out anyway.)
Many had leftover non-default constructors/ assignment operators, and some were initialized, even though the initialized data was never used.
In case of FCycler this even caused a default setting to be overwritten when used inside FDynamicLight.
