Subject: [PATCH] Acq Batch update UI

First UI to use new middle layer batch updater.  On success, this batch
updater just reload the whole page, but it can be made smarter later.
The UI only appears on POs for now, and is partly disabled if the PO has
already been activated.

The API call behind it returns the ID of each line item updated, so we
could really just update the current page, especially if in the future
we simplify the copies interface behind the li_table.
