Comment 31 for bug 1502292

I'me made a slight rework of this to address the issues brought up. The branch can be found here: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/khuckins/lp1502292-add-volumes-from-bib-record-rework

Now all fields should auto populate as expected, and as a slight simplification of the previous code, the Add Volumes button will now work like the Add Volumes action if volumes are selected in holdings maintenance.
