Subject: [PATCH] Provide an option to disable entity metadata rewriting
The work here is derived from the research and guidance of
various members of the minecraft community
This patch provides the ability to disable entity remapping,
which creates various incompatability issues with mods, however,
may also create various issues with mods which do not support this,
hence why the configuration option is provided
