This PR adds key management for lists where changing the focus is not desired. There are now two types of key managers: FocusKeyManager (which will set focus) and ActiveDescendantKeyManager (which will simply set active styles and manage a11y through activedescendant). The latter will be useful for an autocomplete so the text field can retain focus while iterating through the list.
