Title: Adds "liveloading" to the adapters

The new `ExternalContent` model allows mulberry to pull in content dynamically using an adapter, during runtime. Once a node has loaded in an `ExternalContent`'s data, it executes a connection stub `externalChildrenAdded`, which components can listen for to update their list of child nodes.

Refactoring of these components has NOT been done in this pull request.
