Fixed DecalCull components not showing decals at all at lowest quality settings
This component was multiplying the culling distance by Mesh.lod intead of Mesh.quality, Mesh.lod can be set to 0 so it was always disabling decals
This will technically hurt performance on low settings as they weren't showing decals at all, so I've added a minimum 0.25 quality level
Decals on low settings now pop in pretty obviously, but at least they render when up close
Added an editor inspector to show the current camera distance and culling distance, similar to other LOD components
