Do not load all components from a base

[AJamesPhillips]

Currently

• All the components and views of a base are loaded.

Description (acceptance criteria)

• Only load the:
  • knowledge views (to populate the breadcrumbs)
  • for the knowledge views that also have a component that represents them, then load these components
  • the components on the currently selected knowledge view
  • the knowledge views associated with the components on the selected knowledge view (this will only occur when the knowledge views are from a different base otherwise they will already be loaded)

Why (hypothesis)

• Will reduce load times.

Depends on #228.
