Item system is dated

CMDBOOK-2388 - Reported by Dark_Arc

Currently CommandBook's item system is very dated and supports only basic operations. The goal of this bugs is to track the progress of updating this system.

The current concept I am planning involves the support of this new functionality through a new component dedicated to item management and resolution.

This new component must enable support for as many elements of items in vanilla minecraft as possible under the bukkit API, and also allow external mods to add in their own "custom" items which they can define specific build instructions for based on a name based item matching system.
