Drop manual isEditable copy in CraftSign
Signs no longer have a specific isEdiable state, the entire API in this
regard needs updating/deprecation. The boolean field is completely gone,
replaced by a uuid (which will need a new setEditingPlayer(UUID) method
on the Sign interface), and the current upstream implementation of
setEdiable simply flips the is_waxed state.

This patch is hence not needed as it neither allows editing (which will
be redone in a later patch) nor is required to copy the is_waxed boolean
flag as it lives in the signs compound tag and is covered by applyTo.

Subject: [PATCH] Configurable chat thread limit
By default, spigot shifts chat over to an unbounded thread pool,
on a normal server, this really offers no gains, the creation of a thread
on submitting to the pool on these servers eats more time vs just running it in
the netty pipeline, however, on servers using plugins which do work in here, there
could be some overall benefits to moving this stuff outside of the pipeline.
In general, this patch does two things:
1) Exposes the core size for the pool, this allows for ensuring that a number of threads
sit around in the pool, mitigating the need for creating new threads; This IS however
caveated, the ThreadPoolExecutor will ONLY create core threads as they're needed, it
just won't allow for us to dip back under the # of core threads, this can potentially
be mitigated by calling prestartCoreThread, however, I'm not sure if there is much justification
for this
2) Exposes a max size for the pool, as stated, by default this is unbounded, for most
servers limiting the size of the pool is going to have 0 effects given how fast chat
is actually processed, this is honestly really just exposed for the misnomers or people
who just wanna ensure that this won't grow over a specific size if chat gets stupidly active
