this makes bloom, haze (fog), and AO configurable in the Graphics app. like shadows, they can all be set independently in the "custom" configuration mode, although like shadows, bloom and AO only work for the deferred renderer. this also adds a checkbox for enabling procedural materials on models at the bottom of the Graphics settings, and changes it to default on.

• determine if we want to add tonemapping options too
