Bukkit

• Updated for 1.4.6-R0.3
• You can now add Enchanted Books to shelves
• You can now add Maps to shelves
• Saving books is now asynchronous (won't lag server, only the shelves.)
• Added debounce (See caveat 2)
• Shelves cannot be opened while sneaking. I plan on expanding this to allow the placement of signs on shelves.

Update your config and check out the new permissions!

1. If you are using an unlimited bookshelf and you are giving out maps, everyone will see the same map, and everyone will see eachother on the map. This could be a bug or a feature, but it has been around Minecraft since Maps were released.

2. If someone closes a bookshelf, nobody can open another bookshelf until the books are saved. This may be quick or slow depending on how many items are in the shelves, and how much data they contain. A book with lots of pages will take longer than a book with one page. Unlimited shelves do not have this issue, however. I may switch over to yml instead of sqlite depending on if yml is faster or not.
