Comment 11 for bug 1761222

Thanks, Remington.

Follow-up branch pushed:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1761222-holdings-due-date-etc

This contains sign-off's for Remington's commits. It also adds another commit which changes how we fetch the circulation data for the copies in the holdings grid.

Over concerns of launching too many (1 per copy) parallel pcrud requests, I've modified the code to make a single batch PCRUD call. This has the added affect of only displaying due date information for copies that have a non-checked-in circulation, consistent with the XUL client, instead of the last circulation, regardless of its disposition.
