Remove Static Configuration Class and .NET Core Prep (#2122)

* Remove static configuration class that required prior knowledge of when it was initialised to dependency injected method that ensures all configuration has already occured.

* Specify a different log name for the updater, require a path when running the Jackett updater

* Update to all .NET Standard packages

* Explicitly specify the restore project style

* Move automapper out of the  DI framework and put crude detection to prevent it from initializing more than once.
