Fix patch "Faster redstone torch rapid clock removal" (#2014)

Browse Source 
Tux pointed out the patch still has O(n^2) time complexity since
the sublist class in arraylist does not override clear() from
AbstractList, which uses a forward moving iterator to clear
the list.

Resolved by using a peek and poll from ArrayDeque.

This patch also removes the useless WeakHashMap which holds
the list (it mapped world->list) and replaces it with a
field on World.
