Update metadata visualization

[gspinaci]

The metadata display should be similar to Francesco's design. Since we do have space for two columns of metadata perhaps the fist section (Starting with date, ending with Transcribers) could be in two columns. Subjects mentioned don't need the bubble background and should be links that take you back to the search page with that filter/facet activated.
We are currently missing some of the fields from the spreadsheet and these should be added (e.g. notes, accompanying material)

Also it must have archival references
