Move evaluation to a separate Elixir runtime (#20)
* Isolate evaluation in separate node for each session

* Start new remote upon first evaluation and handle nodedown

* Add UI for managing evaluation node, improve naming and structure

* Show runtime initialization errors and some fixes

* Improve standalone node initialization

* Correctly handle multiple sessions connecting to the same node

* Fix session tests concerning evaluation

* Documentation and some refactoring

* Various improvements

* Configure schedulers to get to sleep immediately after evaluation

* Move EvaluatorSpervisor into the Remote namespace

* Fix evaluators cleanup

* Add tests

* Improve flash messages

* Introduce remote genserver taking care of cleanup

* Redefine the Runtime protocol to serve as an interface for evaluation

* Cleanup operations

* Use reference for communication with a standalone node

* Use shortnames for distribution by default

* Update node configuration and make sure epmd is running

* Rename Remote to ErlDist
