- CSoundPatch:ChangePitch() is now networked.
- CSoundPatch:ChangeVolume() is now networked. This fixes infinite thruster noises and maybe other sound loop bugs.

- Fixed pure clientside sounds with no parent and position data causing errors (this fixes the radiation sound bug).
- No longer delay sound networking by a tick.

Another sanity check when first starting a map, where local player can be nil.

Minor sanity check.

- Fixed looping sound not stopping in various cases. Please report if more occurrences pop up.
- CSoundPatch networking.
- Fixed NPC dialogue not playing.
- Fixed duplicated footstep sounds.
