With everything moving away from magical values to MinecraftKeys, it has became necessary to represent minecraft identifiers ("keys" or "resource locations") in an API form.

Things like Mob Spawners and Spawn Eggs need things listed in the new string group:name format, but nothing exists on the Bukkit API to represent those.

I propose a new "Identifier" class is created to be the Bukkit counterpart to the MinecraftKey class that represents an object that has a group/name relationship.

This API, once added, can then be used to expand other API's to utilize them.

Examples:

• Mob Spawn Eggs
• Mob Spawners
• Loot Tables
• Materials / Block Identification
