Bug 19585: Inventory: Allow additional separators in a barcode file

This patch makes \n, \r, |, comma, semicolon and hyphen ('-') all valid
separators between barcodes passed to inventory.
An additional grep removes empty barcodes. (Note: The grep looks for at
least one non-whitespace character. We could be more specific, but this
allows for more flexibility like testing with alphanumeric barcodes etc.)

Test plan:
Upload a barcode file that contains various allowed separators.
