[SonikkuA-DatH]

Resolves #3588
Gives the Water + Grass combo a unique swamp animation for the lingering effect

Also tweaks Sea of Fire to fade bg and mon palettes for its set effect

Could the Swamp end of turn effect go BG fade in -> Rain effect -> green shake -> BG Fade out?
Right now I think it looks a bit strange with the half fade(?) then rain then the BG.
