Changed calculateDelta() so when unchecking a task it removes the right amount of gold and exp
fix(memleak): add a "nullify" function to user wrapper. This is stupid,
find a better way. See HabitRPG/habitrpg#4079
feat(backgrounds): october backgrounds
feat(spookDust): add the spookDust special spell, like snowballs. Note: this is handled specially so spookDust can be bought with GP, is a WIP

fix(spookDust): rename to spooky sparkles
