Bug 29491: Improve display of notices in patron details

This patch updates the patron notices list so that notices are shown in
a modal dialog instead of inline in the table. The "Resend" button is
shown in the modal window controls.

To test, apply the patch and locate a patron in the staff interface with
multiple sent notices.

- View the patron's "Notices" tab.
- In the table of notices, click one of the notice titles.
- A modal window should appear with the notice subject as the header
  and the notice content in the main body of the modal.
  - If the message has any other status than 'pending' there should be a
    "Resend" button in the modal footer. Confirm that it submits the
    form and resends the correct message.
  - Try viewing multiple notices to confirm that the contents of the
    modal are correctly updated for each message.
