Subject: [PATCH] Bug 20770: ILL loans OPAC form notes field allow arbitrary
 input

This patch addresses the lack of sanitization of the "notes" field on
the OPAC "View Interlibrary loan request" page.

To test:

- Apply the patch
- As an OPAC user, create an ILL request
- Navigate to the request's "View Interlibrary loan request" page
- Add the following note:

  Hello
  <h1>TESTING</h1>
  <script>alert('pwned');</script>

- Click "Submit modifications"
- TEST: Observe, when the page reloads, only the following is preserved in the
"Notes" textarea:

    Hello
    TESTING

- As a staff user, naviate to the ILL requests table
- Select "Manage request" for the request you created
- TEST: Observe that the Notes field only contains:

    Hello
    TESTING

- TEST: Observe that no Javascript alert is displayed
