Make generic, removing dependency on node_runtime (#1)

* Extract error to file

* Update readme

* Extract Rpc to separate file

* Make Rpc generic over Runtime

* Editor config etc.

* rustfmt

* Remove node-runtime dependency, generic soup

* Move generic trait bounds to impl

* rustfmt

* Remove unused stuff

* Add test for balance transfer call
