DisableLookAtAnimation debug setting clarification

Not necessarily a bug as it's likely working as "intended", but I suspect this feature might do more harm than is ideal currently. The original request for this feature was meant for those who essentially wish to opt-out of the client driving the LookAt animations for their avatar, but in its current state, residents may consider using this feature for one of the following reasons that it is not intended for.

DisableLookAtAnimation:

• Turns off all LookAt animations locally, including those of other avatars who may actually want to use LookAt for its intended use (looking at things)

DisableLookAtAnimation does NOT:

• Hide LookAt animations when viewed by others

• Prevent LookAt from being broadcast

This is fine for debugging purposes, but for those meaning to use it to disable LookAt animations for their avatar permanently (including when perceived by others) it's not ideal. It also "breaks" the LookAt feature for others entirely who do intend to use it for its intended use.

No file or test is named. Start by tracing the DisableLookAtAnimation setting through local LookAt animation handling and broadcast behavior, then determine the intended distinction between disabling local playback and preventing an avatar's LookAt from affecting others. Done should include clarified behavior and coverage for the affected cases.
