Bug 17055 - Add classes to different note types to allow for styling on checkins page

Returned items may have 3 kinds of notes, patron, item public, and item
non-public. However, the html markup for them does not allow us to
distinguish which type we are seeing. It would be good to add classes
for each of these note types.

Test Plan:
1) Check out an item to a patron
2) Add a patron note, a public item note, and a non-public item note
   to the patron and item you used
3) Check in the item and instead the html, note the each note span
   now has a class to distinguish which type of note is being displayed.
