Blocks have the wrong sounds, eg.

• All Blood Stained Blocks make the grass sound
• All Nether Monster Eggs make the stone sound (soulsand needs sand sound)

Not applicable anymore as of 3d72f73.
Blood stains are removed before the block itself, so the sound is always correct.
Nether monster egg soulsand sound can stay like this IMO.

Quite a lot of work to get this working in the current system of inner blocks, does not seem like a real bug. Other things have priority for now. (Will leave this open if someone else wants to fix this anyways)
