editing legacy skies.

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.

It seems newer compilers have a different interpretation of exactly when to
engage LLSDArray's copy constructor. In particular, this assignment:
some_LLSD_map[key] = LLSDArray(...)(...)...;
used to convert the LLSDArray object directly to LLSD; now it first calls the
custom copy constructor, which embeds the intended array within an outer array
before assigning it into the containing map.
The newer llsd::array() function avoids that problem because what it returns
is already an LLSD object.
Taking inventory of LLSDArray assignments of that form turned up a number of
workarounds like LLSD(LLSDArray(...)). Replacing those with llsd::array() is
both simpler and more readable.
Tip of the hat to Chorazinallen for surfacing this issue!
