Infested blocks drop experience when broken with a Silk Touch tool

Breaking any of the silverfish-infested stone blocks using the Silk Touch enchantment should drop experience orbs (in addition to the regular block). This would make infested stone farms more useful, and give you a small bonus while mining in mountain biomes or strongholds. It also makes sense because using Silk Touch basically kills the silverfish inside the block (at least as I interpret it), and killing silverfish gives xp.
