Added IK support for R15's in animation editor

ChatService:RegisterChatCallback(Enum.ChatCallbackType, luaCallbackFunction) will now allow you to set callback to interact with specific chat message processing steps.

Performance update in ChatServiceRunner server script and Speaker module script. Remove several uses of BindableEvent, and instead just invoke the appropriate lua functions directly. If you have made a personalized copy of the chat scripts we recommend that you review them and reduce uses of BindableEvent, and/or that you minimize the data you send with chat messages as extraData.

Apple mobile devices with retina screens and iOS 8.0 (iPad Air, iPhone 5S) will no longer use antialiasing or high-quality shaders when rendering 3D content; players need to upgrade iOS version to 9 or above to get these effects back.

Fix Studio showing a warning about needing to enable PGS for Constraints when PGS was already enabled.

Players:GetUserThumbnailAsync() now has a 500 call per minute throttle.

Fixed a memory leak in the avatar sound replication script.
