allow all character stage control to persist after death in crew battles#814

crews is sick. as someone who only plays solo crews, the coolest part to me is getting sprinkles of character interactions you cant get otherwise. utilizing my previous stock galvan UFO to get an edgeguard i otherwise couldnt, getting lily combos as someone other than maypul, those wacky twitter clips where the orcane player left a puddle onstage and bubbles it 2 players later to confirm into whatever. more of those!

let forsburns smoke persist and make the next fighter invisible, galvans drills stay so anybody can do wacky custom combos, wrastors slipstream to chase them down in neutral with new options

i think it would add a lot of personality to a mode focused towards fun and seeing a lot of characters in a short amount of time, while also being specific enough to not change game balance in that game mode too significantly, but thats just me. i would definetly exploit a galvan drill close to the blast zone that makes anyone launched in that direction die about 20% earlier than usual that ALSO persists the whole game because they cant reach it. maybe slap a timer on that one
