Comment 3 for bug 1081551

User-facing fixes pushed to:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1081551-dupe-serial-item-barcode

This includes a check within the serials receive API call to detect and alert on duplicate barcodes and code in the batch receive UI to detect this event and warn the user.

Since these two bits of code are needed to provide any semblance of a meaningful message to the user (instead of DATABASE_UPDATE_FAILED) and they resolve the issue at hand, I have opted not to add the additional DB check within this patch. It would still be a good thing to have, though.
