Added party itemShare mode: EQUAL

Slightly cleaner way of handling equal item sharing.
Reset the item share modifier back to base when a player leaves the party
Added a new config file for the itemWeights
Removed the debug messages.
Added Lapis_Ore to itemweights.yml
Drop the item on the ground if the winningPlayer's inventory is full.
Unneccesary
Added a feature which allows the party leader to toggle item share categories....
That should be the rest.
