Certain messages regarding weeping (arch)angels now make more sense, particularly where their unique gaze attacks are concerned. Also fixed some inconsistencies in applying blank spellbooks and the Book of the Dead.

Minor code fix to avoid a possibly nonsensical message. (How can you know what the weeping angel is doing if you can only see the monster it's attacking?)
