Plugin interfaces (plugins v4) (#615)v1.23.1-rc2v1.23.1-rc1v1.23.1v1.23.0-rc2v1.23.0-rc1v1.23.01.23.X

Replaces the current plugin api with source interfaces.

- backwards compatible
- no more json in binaries (wtf)
- does not rely on structs from third party libraries (wtf)
- actually initializes variables
- no more basically unused classes

The launcher exposes almost everything required by plugins in interfaces that allow for backwards compatibility.
The only thing that's passed to a plugin directly is the northstar dll HWND and a struct of data that's different for each plugin.
