main.js should bind more specific objects to controls

[bsclifton]

Discussed in #3346, more specific objects should be bound to controls inside main.js.

For example with history, the entire sites array is passed on to the about/history page when only valid history entries should be sent.

history={frame.get('location') === 'about:history'
                ? this.props.appState.get('sites') || emptyMap
                : null}

One step forward for mankind with #5559
