Align Document Detail View and Document List View

[richmanrachel]

Document Date, Input Date, and PGPID are currently given the same weight in the document list view:

Whereas, in the doc. detail view, Document Date is rightfully more prominent:

@gissoo - would it be possible to make the list view more consistent with the detail view? Renaming "Input Date" to "In PGP since" and perhaps making the input date and PGPID fields dark gray (rather than black)? This will help users distinguish which information is directly about the document rather than the database.
