Added getNewBannerPatternDesc() into LangUtilsHook.

1. Let getMusicDiskDesc() also use LangUtils.
2. Added the getNewBannerPatternDesc() method.

Forgot to explain, I made some changes to HookManager:

1. I replaced the HookList with HashMap, this can improve performance when there are a large number of Hooks.
2. And a HashMap with the Hook Class as the Key is added, so that the Hook can be retrieved in the manner of hookManager.getHook(hook.class).
