Discord <-> Game relay

[Tenrys]

Rewrite using GWSockets
The one we use currently is crappy, uses HTTP and has a pretty shit API

[KabusDev]

should also try to improve latency between discord chat and ingame chat

[Tenrys]

The only latency that exists is only because of a timer to avoid HTTP rape.

[Tenrys]

Current one is fine.

Let's add mapchange / shutdown notifications

[Tenrys]

That's also done. But now I need to add Github error source file linking, like in Dream Bot Mark II and on the PAC3 server.

[Tenrys]

Let's add lots more commands too.
