[Ore] Magnesium

[Argmaster]

This is a proposal to add magnesium to the game.

Physical properties:

• hardness in Mohs scale: 2.5
• density (at 20° C): 1.7 g/cm3

In game properties:

• behavior similar to gemstones - provide special effect instead of stats
• low durability
• low damage
• light

Modifiers

• magnetic: (pun intended!) Attracts items on the ground. Attraction force should scale with amount of magnesium player has in his currently held tool and armor it wears.
• blunt: (if used as a tip) damage delt by tool approaches 1 as durability approaches 0

Spawn rules

• -? < Z < -?
• Spawns in veins

I like the magnetic modifier!

[Argmaster]

After last playtest we agreed that making magnesium magnetic may have unexpected negative impact on younger Cubyz audience, so that idea will be abandoned. Instead we figured out #1325 would be a good replacement.
That said magnesium is still useful as source for brighter (more end game) torches, comparable to current white crystals. Maybe we can figure out something else on top of that.

While torch progression is a compelling use-case, we don't necessarily need Magnesium for that, and we already have enough metals in the game. So I'm closing this issue for now.
