Subject: [PATCH] Fix possible StackOverflowError for some dispenses
For saddles, carpets, horse armor, and chests for horse-likes
a BlockDispenseEvent handler that always mutated the item without
changing the type would result in a SO error because when it went
to find the replacement dispense behavior (since the item "changed")
it didn't properly handle if the replacement was the same instance
of dispense behavior.
Additionally equippable mob heads, wither skulls, and carved pumpkins
are subject to the same possible error.

Subject: [PATCH] Protect Bedrock and End Portal/Frames from being destroyed
This fixes exploits that let players destroy bedrock by Pistons, explosions
and Mushrooom/Tree generation.
These blocks are designed to not be broken except by creative players/commands.
So protect them from a multitude of methods of destroying them.
A config is provided if you rather let players use these exploits, and let
them destroy the worlds End Portals and get on top of the nether easy.
