SL-20654 Fix for box probes sometimes glitching out at the corners.  Incidental fix for crash when mWaterPool is null.

SL-20258 Fix for LSL spamming new probes into the scene deadlocking probe updater.  Add probe update debug display.

SL-20124 Wipe reflection probes when applying parcel EEP settings and pause updates on probes until transition completes.

On standard reflection probes this doesn't really do anything.

Still need to fix the problem with individual faces getting tossed around though.  Will work on that tomorrow.

DRTVWR-559 Fix for manual probes not updating as often as they should when nearby (bad distance calculation)

DRTVWR-559 Revert skies to be very close to release and disable tone mapping when probe ambiance is zero.

Hack for desaturating legacy materials has been removed for performance and quality reasons.

Adds a new setting for auto adjusting legacy skies.  This is the PBR "opt out" button.  If disabled, legacy skies will disable tonemapping, automatic probe ambiance, and HDR/exposure.  If enabled, legacy skies will behave as if probe ambiance and HDR scale are 1.0, and ambient will be cut in half.  

HDR scale will act as a sky brightener, but will automatically adjust dynamic exposure so the sky will be properly exposed.  If you want relatively even exposure all the time, set HDR Scale to 1.0.  If you want a high range of exposures between indoor/dark areas and outdoor/bright areas, increase HDR Scale.

Also tuned up SSAO (thanks Rye!).

Reviewed with Brad.

DRTVWR-559 Remove RenderReflectionProbeCount (which is bugged) and lean on RenderReflectionProbeLevel for preferences (which works).

DRTVWR-559 Add control for automatic reflection probes to advanced preferences and featuretable. Remove Reflections checkbox.  Don't persist reflection probe volume display between sessions.  Incidental decruft.
