Title in middle pane should display "type" for manuscript item type if manuscript has no title

[erazlogo]

if a manuscript has no title, there is usually a general description in the "type" field, cited like this:

Release form signed by parents of James Hillard Houser, Vale, NC, 18 November 1940, box 14, folder GB 220, WOR.

this description should be used to display title in the middle pane if there is no other title
