Enchantment volume calculation

[Nando Neck]

It would be nice if the volume calculation can be done for enchantments and the values are shown.

e.g. bindungdesstabes → Staff volume = 0/18

+ astraltransfer → Staff volume = 3/18

+ astralentzug + astralraub + bannstabdesadepten + bannstabdesmagus → Staff volume = 21/18

+ volumenerweiterungdeszauberstabs * 3 → Staff volume = 21/21
