Deferred fastalpha behaves a bit better.
Pulled over patch for https://jira.secondlife.com/browse/STORM-336 and https://jira.secondlife.com/browse/STORM-1011 from linden repo
Sky rendered using new LL method. Assuming this fixes issues on AMD cards(works on cat 11.2)
Added a few things missed related to spatial-parition updating.
Added 'SkipReflectOcclusionUpdates' setting that prevents occlusion updates for reflection pass. Less taxing on CPU.
Fixed avatar shadows on AMD (and any other sane GLSL compiler)
Fixed windows compile:
-curl version was updated after running develop.py. Not sure if applicable to linux/darwin
-new llqtwebkit version on windows, since the old url is now invalid.
