Mob banish on touch + GMS-like cosmetics + Clear missing names
Fixed erroneous clean slate scroll block on equipments having certain properties. Implemented a log for bought cash items from Cash Shop. Implemented mob's player banish by touch (e. g. used by mobs from the Hypnotize quest). Thoroughly revised stylist/surgeon NPCs, adding several missing GMS-like cosmetic contents. Thoroughly revised String.wz names having missing item content throughout the WZ files. Revised missing name info for several faces throughout the WZ files. Solved a possible deadlock case related with a player vision's spawn object method. Fixed an issue with "Movement allowed only within account" items being given as "Untradeable" by NPCs. Happy Holidays and Great New Year everyone!!!
