25ce0f6d82 Rewrite /lair command
This wasn't strictly necessary as this command has outlived its
usefulness, but I had gone ahead and rewritten it because it was (barring
taskStart()) the only place in the codebase that accesses Chunking::chunks
outside of Chunking.cpp. This became apparent during a (currently paused)
effort to improve the API that the Chunking namespace exposes to the
rest of the codebase.

I went ahead and rewrote the rest of this command as it was poorly
implemented anyway. This has been sitting in my working directory
uncommitted for a few months, so I may as well push it.

Mobs can now get criticial hits
Explanation: it was uncertain whether mobs could perform critical hits, since the color of damage numbers didn't change at all. However, I found that male characters will actually use a different sound effect when receiving a crit (I confirmed this SFX appeared in old FF videos), so I went ahead and re-enabled it.

5c1bb0acc9 Add enabledpatches config option
The server administrator must now specify which patches they want the
server to load (if deviating from the defaults). There are multiple
reasons for this:

* It's useful to be able to pick and choose which patches you want to
boot the server with; without having to move the directories in and out
of the patch directory
* This way, we can have different default patches for different builds
of the game (104 vs 1013)
* ...ergo, it's easier to rapidly switch builds without having to
rearrange your workspace to properly run them
* This also allows us to remove the std::filesystem stuff, which has
spotty compatibility with slightly older (but still current) versions of
the compilers

their namespace. All redundant namespace prefixes found have been

d5fe1cc513 Work around not being able to reach the shard from a local connection
In certain circumstances, like when running a private server through
Hamachi, the shard IP will be set to an address the local machine can't
reach itself from, preventing only the local player from getting past
character selection. This workaround detects local connections and
sends a loopback address for the shard instead of the configured one.
This makes those use cases feasible.

da8dde9818 Do not dynamically allocate memory in CNSocket::sendPacket()
Also reorder the rapid fire check in MobManager::pcAttackNpcs(), so the
output packet validation happens immediately before the buffer is
initialized, for clarity.

217168fe50 Improve DB and Nano sanity checks
I'm aware that the DB checks still allow ID 0 items and Nanos, but the
point of those is primarily to prevent invalid memory access.

b87229aa65 Reject requests to equip items into the wrong slot
This is important because the client can genuinely send such an invalid
packet by mistake during normal gameplay.

If a sanity check fails, we don't need to send any sort of "move it but
keep it where it is" packet, since simply ignoring the invalid request
doesn't softlock the client.

Also improved validation of inventory slot indexes.
