Bug 35689: Add id and classes to each MARC note in OPAC bibliographic details

Building on Bug 14156, this patch updates the OPAC bibliographic
detail page's display of MARC notes to add the tag number in both a
class (for consistent styling across the same tag number) and id (for
unique styling for each repeated tag).

To test:

- As a quick test for custom CSS, go to Administration -> System
  preferences and locate the OPACUserCSS preference.
  - Add this testing CSS:

   .marcnote { font-size:140%; font-family: serif; }
   .marcnote-500 { background-color: #66FFCC; }
   .marcnote-511 { background-color: #99FFFF; }
   .marcnote-520 { background-color: #CCFF00; }
   .marcnote-521 { background-color: #CCFFFF; }
   .marcnote-538 { background-color: #FFCCCC; }
   .marcnote-546 { background-color: #FFFFCC; }

- Locate a record with multiple notes fields. In the sample data, record
  46, "Viridiana" is a good example which works well with the above CSS.
- On the bibliographic detail page for the record, click the
  "Descriptions" tab.
  - Each MARC note should be colored according to the tag it comes from.
  - Inspect the HTML to confirm that each paragraph also has its own
    unique ID.
