fixed issue with insanity bar not returning. or setting ot the player if they are in the target world already on reload

added insanity level save function to keep note of the last known insanity level upon leaving the target world
this function will also recall last saved insanity back to the player upon return to the target world

new command /checkinsanity <player> will check if the player has a saved insanity level and recall it to the targeted player

all commands will require the permission node apocolypse.admin unless opped
