Misc Polishing (#413)

* Ensure that after we assign a role to a user, we show it immediately

* Cached libraryType api as that is not going to change in a viewing session. Moved some components around to tighten bundles.

* Cleaned up more TODOs
* Refactored Configuration to use getter and setters so that the interface is a lot cleaner. Updated HashUtil to use JWT Secret instead of Machine name (as docker machine name is random each boot).
