Put the decompile fixes into MC Dev Fixes patch
Optimize RegistryID.c()
It's possible we won't hit this on the servers current state since nothing is async,
but we are working towards that.
I experienced a crash due to this code during my work.
Our changes for the spawn radius have the potential to throw an ArithmeticException
should the server be stopped before we've loaded worlds, we check if the server is
running earlier to check if we should even consider attempting to load chunks, which
would cause us to, 1) not load chunks anyways, as we're disabled; 2) throw an
ArithmeticException due to us expecting that we're going to be loading more than 0 chunks.
These chunks are unfinished, and waste cpu time saving these unfinished chunks.
the loadChunk method refuses to acknoledge they exists, and will restart
a new chunk generation process to begin with, so saving them serves no benefit.

Duplicate UUID Resolve Option
Add more information to Entity.toString
change LAST_EDIT to PAPER_LAST_EDIT for edit commands
Add more information to Entity.toString()
Add Debug Entities option to debug dupe uuid issues
Guard the Entity.SHARED_RANDOM from seed changes
Create a symlink on not-windows to current minecraft decompile dir
Due to a bug in 2e29af3df0
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
that an entity might actually change the seed of the random object.
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
every entity to use a Random object with a predictable seed.
This has caused entities to potentially generate with the same UUID....
Over the years, servers have had entities disappear, but no sign of trouble
because CraftBukkit removed the log lines indicating that something was wrong.
We have fixed the root issue causing duplicate UUID's, however we now have chunk
files full of entities that have the same UUID as another entity!
When these chunks load, the 2nd entity will not be added to the world correctly.
If that chunk loads in a different order in the future, then it will reverse and the
missing one is now the one added to the world and not the other. This results in very
inconsistent entity behavior.
This change allows you to recover any duplicate entity by generating a new UUID for it.
This also lets you delete them instead if you don't want to risk having new entities added to
the world that you previously did not see.
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.
It is recommended you regenerate the entities, as these were legit entities, and deserve your love.

This is useful for project developers switching back and forth between
1.12.2 and 1.13 so we can have our IDE automatically use the
current version we are working on for included mc-dev files.
