["Bug"]: Does not keep track of previously broken blocks.

So atm I'm taking notice in my pack that while "CustomDrops" or "DropAnything" is working as intended.
It can't/doesn't keep track of if a placed block has been broken before.

This leads to any implementation that returns the broken block + anything else to be able to be exploited for infinite extra resources.

Example;
In this pack, I'm having X-Logs drop 1 log, 2 bark and 3 sawdust for a base.
This means in theory that I can break 1 log, get 2 bark and 3 sawdust.
Re-Place the log, break again for an extra 2 bark and 3 sawdust, etc.

It's probably not how the mod was intended to be used.
However, the addition of some kind of tracking/JSON option would be a great addition :P.
