Added missing Silver, HC and Unknown molding recipes.
Fixed frog sound. Will only play at night in fresh water surface block, and if there is a grass or water plant block near by.
Fixed a few missing block names.

For the NEI users :)
Added a timer check to food for trimming decay to prevent the player from trimming decay while food is still trying to play catchup from a large time skip.
Added code to make sure that knives are destroyed when handling food.
