Bug 20970: Reformat basket information on acquisitions basket page

This patch reformats the display of information on the acquisitions
basket page, hiding form controls until they are triggered. Some basket
information is now in the second column in order to balance the two
columns better.

The "Library" label has been replaced with the more precise "Managing
library."

Unrelated change: Removed script type attributes.

To test, apply the patch and view a basket in acquisitions. Test these
processes:

- Adding and removing managing users
- Setting and changing managing library
- Setting and changing basket group
