Added bloom and fog controls to bioshock 1 version of RenoDX

- Bloom controls default game's bloom amount. Scales from 0.0 (disabled) to 2.0 (double of the vanilla amount)
- Fog appears to control both shader based fog and "fake" mesh based fog, so it's a global scalar. Similarly to bloom, it scale from 0.0 to 2.0
