Backported from Raze - without this there is no way to implement sounds that can unload themselves, because the existing ChannelEnded function is called when the sound is still active.
src\common\audio\sound\s_sound.cpp(556,27): warning C4244: '=': conversion from 'double' to 'float', possible loss of data

- Sets the direct pitch of the sound to the specific float. Default is 0.0, meaning do not set a specific pitch. Regular pitch is 1.0.
- Only works for direct sound definitions.
- Overrides $PitchShift unless value is <= 0.0
- Overridden by A_StartSound's pitch parameter if the value > 0.0.
With CHANF_OVERLAP this isn't needed anymore - any sound started on CHAN_AUTO can actually play on this channel with overlap implicitly allowed.
This has the added advantage that these sounds can be reliably accessed with other function by using CHAN_AUTO.
