Add Camera Settings

[LukeSaward]

Add camera settings such as Motion Blur, Bloom, etc. for both Normal and Water post-process volumes.

This is how to get to the post-process volumes. . denotes that the thing that comes after it is a field, and : denotes that it's inheritance.

UBP_MyGameInstance_C.WorldReferences.TimeOfDay::ADynamicSky.Volumes[0].Settings
UBP_MyGameInstance_C.WorldReferences.TimeOfDay::ADynamicSky.Volumes[1].Settings

With that, we can make the following options:

Saturation
Contrast
Gamma
Gain
Bloom
    Enable Bloom
    Bloom Intensity
    Bloom Threshold
    Bloom Size Scale
Vignette
    Enable Vignette
    Vignette Strength
