Kyth's Overpowered Moss

This is a small mod that adds one item and one modifier to Tinker's Construct.

It's written against Minecraft 1.12 and TCon 2.8.1.49.

The item, Non-Eutactic Moss, provides a modifier to the tool it's applied to, which in turn follows the following logic:

• Tools heal if in the hotbar but not your main hand.
• Tools will not heal if less than a certain time elapsed since the last usage:
  • If the tool is partially used, this is four seconds.
  • If it's broken, 12 seconds.
  • The weaker the tool, the longer you wait on top of that (50s minus ticks equal to the tool's maximum durability).
• Once healing starts, it takes approximately eight minutes to repair fully, regardless of how much durability that is.

This was primarily inspired by a) how much exp it takes to make the mending moss repair stuff, and b) TCon's old moss that was a superpowered version of the Ecological trait.
