Fixed Errors in Structure Generation

Fixed Errors in Structure Generation and Changed enchantment table to a
researcher. Although @sciguy1121 could you please make it so that the
researcher top changes texture direction when you place it from a
different direction because it looks a bit weird in the lab atm. Thanks!
