Metadata box display

[nichgray]

The shift to display:flex for the .metadata class in the new Orchid release has caused some formatting trouble in the Chesnutt metadata boxes. I added a temporary override for now (ul > li in .metadata now has display: block in the local SASS override file chesnutt.scss), but we may wish to return to this at some point. At the least, even if this override is maintained, there's still some weirdness in the display of the ID number.
