Earmuff Mode Support V8.3A

Please understand that this system is still in alpha and is constantly receiving updates when possible.

For now since I am now aware that earmuff mode is controlled by the Avatar Audio Manger, I decided on replacing the old system with a newer one and removed the ability to control the audio culling on the system. I'm gonna work with this as it's simpler and easier for a user to use within their settings until I find something that I wanna do with it. If this becomes permanent then I might just remove the audio culling all together from the system and make users rely on their earmuff mode.

There is one small idea I have about the system where in the informational area, they can get a popup about how to use earmuff mode instead of having something in the world permanently to clean things up.

Changes

• The audio output of the culled avatar now is controlled with a AvatarAudioOutputManager and now works with earmuff mode.
• Disabled the Audio Culling range menu.
• Disabled Toggle for Visual Mode to disallow Audio mode.
