v0.1

QoS version 0.1

Most of it seems to work and did not so far find anything that does not work.

Either near zero overhead or outright better performance when mod is enabled:

Fast enough, under heavy load compared to pushing a lot of stuff to MT 5.4 and 5.5 internal engine queues QoS works about 12x faster.

Also, while not really significant, HTTP API http.fetch for single request is faster depending on situation (removing timeout enforcement will make it faster for every situation).

Basically that means you can have better control over requests without losing any performance, possibly even gaining performance if you're heavy Minetest HTTP API user.
