Bug 16752 - Remove the use of event attributes from some acquisitions templates - Transfer order

This patch removes the use of 'onclick' from the acquisitions transfer
order process. The patch also modifies the style of some links and
buttons to conform with current guidelines.

- Locate an open basket with items in it
- Click the 'Transfer' link for a title in the basket
- In the pop-up window:
  - Confirm that the 'Cancel' button at the bottom of the window is a
    Bootstrap-style button.
  - Search for a vendor; Confirm that the 'Choose' link is a
    Bootstrap-style button.
  - Choose a vendor; Confirm that the 'Choose' link on the following
    page is a Bootstrap-style button.
  - Confirm that clicking the 'Choose' button transfers the item to the
    correct basket.
