Turnabout Turnabout haha

This ones a doozy.

Completely overhauled the way websockets work, its no longer a stupid proxy and is much much less buggy.
Refactored a ton of API shit to actually be useable and make any kind of sense (Why did I think you could have static interface members?)
Lots of small fixes and improvements like multi-client bans, properly informing the client of updates like taken characters
I put a bit of time into working on backwards compatibility. The server should now be compatible with any AO client from 2.4.3 onwards.
Added case alerts, which technically don't do anything yet but they're in so /shrug.

As always you need the .NET 5.0 Desktop/Core Runtime (Check Server Setup for details).
Windows x64 and Linux x64 provided for now, build your own if you need ARM or MacOS.

I swear i'll set up an AppVeyor eventually
