[dev1244] The /equip text command now accommodates the consolidated accessory slots (ears, wrists, L.finger, R.finger). Subcommands specifying former slots can still be used, but will instead equip to the following slots:

R.ear → Ears
L.ear → Ears
R.wrist → Wrists
L.wrist → Wrists
R.index → R.finger
L.index → L.finger
R.ring → R.finger
L.ring → L.finger
