Support to import and load clojure dependency on loader

[pratik-fractl]

Currently, via loader we can only intern components from each model be it main model or dependency model. But, if design studio wants to have clojure dependency, it must also be imported and made available from loader.

[vijayfractl]

Fractl cannot load clj/java dependencies on-the-fly. For this the model must be build into a standalone jar (which basically produces a customized fractl runtime).
