Added exploit prevention relating to oversized books. Enabled by default until this gets properly fixed from Minecraft side. You can disable it in config file. By default player will be limited to books up to 20 pages, anything over than this gets cleaned out. If players tries to create book over this limit he will get message informing about limitation. You can increase limit by giving permission cmi.book.pages.[amount] or by disabling this protection in general. Would not recommend to disable it until correct patch is issued on server side. 20 pages should be more than enough for regular users and this only has effect on newly created books and will not have effect on locked ones, like ones from ctext or any other you can get though other means.
