AD Durability Tooltip

Displays tool durability as a tooltip.
Extremely minimal (written in 38 lines of java) with ABSOLUTELY NO DEPENDENCIES.

Display format may be edited by overriding the lang vars with a resource pack:

{
   "durabilitytooltip.durability": "Durability: %s / %s",
   "durabilitytooltip.max_durability": "Durability: %s"
}
