After getting horses to go into heart mode, xp comes out, but no baby horse.

Horses move unrealistically slow, they should go faster altogether.

Proposed Properties

1. Can be used (indirectly) for crafting all stone-line constructions (walls, stairs, slabs, micro-blocks)
2. Mineable
3. Can be etched like other certain stone types
4. Used in steel-making as a flux mineral

Conditions

1. Mineable only near the surface or in high y-levels (considering between y-level 48 and 250)
2. Distributed in clusters similar to Bauxite or Malachite but with somewhat greater abundance
3. Can be used in crafting but must first be polished using a belt sander
4. Soft but not quite as soft as quartz in terms of mineability
