Edit screen UI for post formats: a first run for functionality.

* Adds a very basic tabbed interface for selecting a post format (requires JS).
* Extra fields, which are post meta, are shown/hidden based on the selected format.
* Introduce a helper function for retrieving formats-specific metadata: `get_post_format_meta()`.
* Image selection uses the media modal, although without filtering or from URL support at the moment.
