MT Inventory Weight

the calculation system for blocks and items has been redesigned, now the weight of even the same type of blocks or items differs too much.

• blocks: get their value from Blast resistance, Hardness, Transparency
• items: get their value from Max Stack Size and Rarity, if possible from the damage and amount of armor and toughness
• fix tooltips
• new approach for tooltips (entirely reworked)
