Minor update while I work on presets - C13 AEGIS 1.231 (Patreon)

It was brought to my attention that taillight glare was too strong in some instances. I guess i was too heavyhanded when setting things up for the new tonemapping. So here's a minor tweak to the way glare is set up. Overall, it produces a more natural and stable overall look.

Additionally, this improves compatibility with pre preview218 csp versions.
