Fix "prevent players from moving into unloaded chunks"
it used public method instead of private, and moved to world config

also improved the implementation to not use obfuscated stuff

Also removed the Fix Double chest conversion patch since its
fixed in other ways in vanilla

Subject: [PATCH] Don't recheck type after setting a block
The server does a "Did my update succeed" check after setting
a blocks data to a chunk.
However, writes can not fail outside of a hard error or a
a race condition from multiple threads writing, which is
not something that should ever occur on the server.
So this check is pointless, as if it did occur, the server would
be having data corruption issues anyways.
This provides a small boost to all setType calls.
