Implementation of sRGB image support. Overhauls the linearization setup to utilize the sRGB image types, as well as refactors the use of ColorF and ColorI to be properly internally consistent. ColorIs are used only for front-facing/editing/UI settings, and ColorFs, now renamed to LinearColorF to reduce confusion of purpose, are used for color info in the engine itself. This avoids confusing and expensive conversions back and forth between types and avoids botches with linearity. Majority work done by @rextimmy
