WIP: inline ckeditor
Use box-sizing mixing rather than manual prefixing.
Fix show story template when there's no (nil) content.
Fix (mostly for consistency) nil-content story templates in lists
This is probably an impossible case, but it's also consistent with the
single-story template this way.
Remove one level of div nesting for the content editable inline form.
This also simplifies layout.
Enable show-like display of auther+date in edit mode.
Fix created_at timestamp span nesting (styling was incorrectly applied to an empty span rather than the text).
Inline edit mode: also use border for content, just like for the title.
Procfile: specify port explicitly, otherwise the port is order-dependant.
Add an HTML5-like placeholder to the new-story page.

It's a simple but imperfect emulation: once focused, the placeholder disappears permanently.
Remove content css, no longer necessary in inline mode.
Add insert toolbar group; this allows inserting images
Actually allow images in uploaded html
