Feature/autofac tidyup (#2096)

* Move service config service back into shared .NET Framework Library

* Move Content files into shared folder. Make autoface load different assembilies depending on what framework is using it.

* Change my mind on what the shared module should be called. Common Module is too bland.

* DotNet4.SocksProxy is not yet publically .NET Standard. Revert to previous SocksWebProxy package.

* Check in unstaged change to test dependency injection setup.
