XML Spawner rollback for Pub 58 1.0

Support for adding "spawned edits" in the book of the xml spawner was removed for pub 58, this is a sloppy edited version of pub 57's version to work for 58 and gives you back the power to put entries in the book like

katana/name/Excalibur/hue/RND,200,225/attributes.bonusstr/5

or

RecallRune/Movable/False/STEALABLE/True


NOTE: iirc, no edits to other files are required for this to work
