Fixed postures for Printer and Electricity

Somehow the postures for Electricity and Printer got swapped in the reference guide and posture list in Sub/Urban Butoh Fu 3, though the correct postures were used in Saibwahdz and in the oracle deck from The Game Crafter. I'll be fixing SBF 3 soon. I also left out "aur," the word for addition, which is now included.
