Resource pack

The Resource pack system is an upcoming API replacement for texture packs and is a way for players to further customize their Minecraft experience. Resource packs will also allow players to customize music, sounds, lang files,end credits and fonts without any code modification. Ultimately, every mod/plugin will be its own resource pack, vanilla will be a resource pack by itself, and users will be able to apply multiple resource packs at once.Unfortunately, this means that all current texture packs will break... We'll be working on another unstitcher-like tool to aid with the conversion, and hopefully this will be the last major breakage to texture/resource packs in the foreseeable future. We're also including a new metadata format so that we (and mods/plugins) can easily include whole new types of resources with very minimal difficulty and The new format will allow us to more easily detect out of date packs and possibly even load them as if they were up to date.
