Kelsi 4db97e37b7 Add ambient insect particles near water vegetation, fix firefly particles, and improve water foam
- Spawn dark point-sprite insects buzzing around cattails/reeds/kelp/seaweed
- Fix firefly M2 particles: exempt from alpha dampening and forced gravity
- Make water shoreline/crest foam more irregular with UV warping and bluer tint
