Add multithreading (simple alternative to coroutines/async for now)

Reduce worker amount in main test

Update test

Add client port to response in logger middleware

Add file GET shorthand proc

Add client's port to logging middleware

Add client's port to Request type

Remove maxClients (vestigial from async days)

WIP

Separate log handler thread working

WIP: making multithreaded logging chronologically-accurate

Seems to get really good performance

Still runs with single-threaded performance even with multiple threads

ARC works just fine. ORC has issues with my usage of threads for some reason.

Get rid of Malebolgia (plain threads work great when following
httpbeast's approach), still socket deadlock issue

WIP: fixing garbled sockets data (race condition probably)

Multithreaded per-connection spawns via Malebolgia (issue with
concurrent requests and low performance still)

WIP: issue with file descriptor not existing on recvLine when parsing request

Close to functional threading -- compiler error with newServer
