`spestudied' manipulation again (trunk only)

     Refine last week's change dealing with polymorphing spellbooks:  when
a spellbook has faded to blank after multiple readings, randomize its
spestudied value so that it doesn't always polymorph into another blank
book on the first subsequent transformation attempt.
