ACQ PO inline details view

Adds a new 'expand' lineitem option which produces a table inline below
the lineitem title, author, etc. containing copy information.  Each copy
linked to the lineitem is represented as a row in the table with owning
lib, copy location, fund, barcode, callnumber, and notes.  An option to
expand/collapse all is also present.

Release notes included.
