Implement UI for listing authored stories

Implement a UI for seeing an authenticated author's stories. This is, in effect, the Manage Stories page that was mocked up in the most recent round of designs (see attached screenshot).

The listing should include published and unpublished stories separately, though efforts should be made not to exclude a combined listing from being produced.

This listing should also include the ability to select a story to edit (see SJRK-407 and SJRK-410 for details), and to delete a given story (SJRK-406).

The server-side aspect of this work is SJRK-408.
