TPAC: Get rid of all unneccessary uppercase and some bold

This gets rid of all places in the TPAC where CSS uses text-transform:
uppercase or capitalize.  The former is bad for readability, and the
latter can only confuse users when strings might appear to be
capitalized differently in one context than another (esp. users'
personal names).

This mostly, but not exclusively, affects the My Account section.
Also, one wholly unused CSS class was removed altogether.

It also gets rid of some bold style that was applied too liberally to
the whole contents of tables.

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.
