Made it so that sounds are harder to be muffled when sound bouncing isn't enabled.

Sanity check.

Added entity parent and children to anti self occlude filter.

Fix for infinite looping sound when a soundpatch becomes an orphan.

- Potential fix for sounds randomly going missing.
- Go back to using unreliable net channel for performance and bandwidth sake (I think?).
- Small optimization in the way the addon stops looping sound played on CHAN_VOICE.

- Reverted looping sound change.
- Better IsPlaying functionality preservation.

Invalidated predicted sounds table after a bit to prevent it getting ridiculously large.

No longer network looping sounds, since a sound's effect can only be set at the moment it's emitted. This can result in infinitely muffled sound, or sounds getting muffled when it doesn't make sense.

Minor sanity check.

- Allow vanilla CSoundPatch functions to run too, since it already cannot play due to EntityEmitSound hook intervention. This should fix functions like CSoundPatch:IsPlaying() from returning incorrect value.
- Fixed a dumbass mistake where serverside sounds are not blocked.
