Write internal API Client and add all API types

[ShadowJonathan]

This has been corroborated with the matrix room; I'd like to rewrite the internal API Client (the functions and data models) that calls out to the Lemmy servers.

I'll put the application Logic under Logic/Networking/Lemmy Interface, and the data models under Models/Lemmy Interface.

Doing this correctly is a bit of a challenge since Lemmy currently does not have HTTP API Docs, but ill reverse engineer the API from the rust source.
