Bug 16592 - Use Bootstrap modal for MARC and Card preview on acquisitions receipt summary page

This patch replaces Greybox modals on the acquisitions receipt summary
page with Bootstrap modals.

To test, apply the patch and go to Acquisitions -> Invoices -> View an
invoice ->  Go to receipt page.

- In the list of pending orders, test the "MARC" and "Card" links for
  various titles. Each should trigger a Bootstrap modal with the correct
  content.
- Repeat the same tests in the list of already received orders.
