Crimson Swords

Added new repair item:

- Diamerald (recipe doesn't work in JEI, so I'll explain here and on the front page)

    - When used in the anvil with a weapon/tool/armor piece, it will cost 3 levels and the diamerald in order to completely reset the repair cost of the item which can be very helpful if your item gets to that point where doing anything with it will be "Too Expensive!" Hopefully, this should allow you to avoid that annoying possibility

Added new Tier of items (and blocks):

- Mythril Ore

- Raw Mythril Ore

- Mythril Ingot

- Pure Mythril Ingot

- Flimsy Mythril Hammer

- Mythril Falchion

- Mythril Broadsword

- Mythril Dagger

- Mythril Lance

- Mythril Gauntlet

- Mythril Helmet/Chestplate/Leggings/Boots

- Mythril Axe/Pickaxe/Shovel/Hoe

Added new blocks:

- Steel Block

- Cobalt Block

- Raw Cobalt Block

Fixed enchantment:

- Weightless was granting higher fall damage when jumping for some reason, so I went and modified the entity gravity "fall distance" for anybody wearing the enchantment. Should work better now.
