v2.0.0 - Mar 17, 2013
Complete plugin rewrite!
Players now receive any book they have not yet received when joining the server. Add a new book, and players will automatically get it on join even if they have received other books before.
Books generated by this plugin are now blocked from being traded with villagers (configurable).
Added command to give books to other players.
Added command to unsign books.
Books may now be specified by number or title in commands that require a specific book.
Fixed update checker to only show up if there is a newer version available.
NOTE: The structure for books.yml has changed slightly. The plugin will automatically convert your old file to the new structure the first time you run it.

Slightly changed the way books are stored. No more missing numbers if books are deleted! All are stored in order now.
The plugin now automatically checks for a new version, and notifies the console, server ops, and anyone with the bookrules.receivealerts permission. This can be disabled in the config.yml if you do not wish to receive these notifications.
v1.2.0 - Sep 03, 2012
Fixed players being given books upon every login.
Fixed the "Welcome-Message" config value not being added automatically, causing the [BookRules] null message on login.
Added a config to change the delay in seconds before users are given the books, for compatibility with AuthMe, StarterKit, etc.
Added Metrics for anonymous plugin tracking. Opt-out by editing plugins/PluginMetrics/config.yml and change opt-out to true if you so wish.
v1.1.0 - Sep 01, 2012
Added delay before giving players books when first joining. This allows the welcome message to be shown, as well as providing compatibility with other kit plugins that may be used alongside this plugin.
