TPAC: Display public hold notes in user holds list

TPAC: Display public hold notes in user holds list

If a given hold has a note marked as public, and not marked for staff, then
display the note in the My Account -> Holds list. This enhancement also
includes sample notes for each hold, to include data that ensures that the TPAC
does not display any hold notes that are not marked public, or which are marked
for staff.
