Title: Changed Mese to act like an object cut out of a block of stone, rather than an object found *among* the stone.

That is, mese should behave such that you get something potentially out of the block you just broke apart, rather than just collecting the whole block when mined. In principle, this is similar to iron, coal, etc. but you get a crystal rather than an ore, which should be useful by itself in some newer recipes.
