Added conditional visibility params to some global settings, and exposed new fast live render param.
Made changed to allow Live Renders to now work correctly.
Changed some shader params to be float sliders in Katana's interface.
Changed recursive SG iteration logic for transforms of assembly and instance source types to limit the depth that transforms are built to (upwards), in order to not accumulate the same transform twice at both the leaf and source level. Also made some SGLocationProcessor functions protected.
