[Suggestion] Add item deconstruction via Crucible

[grundyboy34]

Item deconstruction is something that many players would love to have. I have an idea for a simple implementation for it in slimefun which I'll describe below, and could help implement it if requested.

1. Expand Crucible handler to detect if an armor piece or a weapon has been used on it.
2. Find the item's recipe and send the number of ingot's required to create it to the calculation below. (Use the base item as a fall back. Cobalt armour to iron for example)
3. Calculate the amount of ingots to be received by multiplying the ingots required to create the item by the durability as a modifier and rounding to the nearest whole number.

Example 1:
Item - Cobalt boots - 65% durability
4 Ingots * 0.65 = 2.6 ~= 3
Output: 3 Cobalt Ingots

Example 2 (case in which recipe was not detected):
Item - Some item (could be from another mod) whose base item is iron boots - 37% durability
4 Ingots * 0.37 = 1.48 ~= 1
Output: 1 Iron Ingot
