V1.3: Tool & Armor Refinement

Tools and Armor will repair themselves if they are in the players main inventory (for armor they can also be worn and repair while worn).

Slight increase in tool and armor repairing.

Tools have been refined to remove the optional dependency on _mcl_autogroups just for timings.

Version 1.2: Resource Difficulty

Now it's greatly difficult to get these tools/armor in MCL and MTG, as
it now costs 9x9x9 leaves to make 1 piece of the tool or armor.

Also reworked the MCL armor and tools so they should properly work
regardless of MCL version.

Version 1.1: Rebalance

I have balanced the repairing on tools so in MTG and MCL they repair the same amount.

Armor remains unchanged as it is already the same amount. Just different methods of achievement.

Version 1.0: Inital

Behold self-repairing tools and armor won't fail you like regular armor and tools.
