Bug 4162 The inventory tool lacks validation for barcodes

The inventory tool had no form of validating on what was assumed
to be a valid barcode number.

To solve this, an extra loop to read before processing was added.
This allows to validate length and content. By using a check
of \p{Print}, this includes Unicode characters such as umlauts,
but excludes unusual control characters.

The template was modified to accomodate validation messages
related to the length and content errors. Additionally, it says
how many "barcodes" were read. Barcodes are supposed to be on
separate lines.

TEST PLAN
---------
1) Attempt to select a file which does not contain barcodes and
   is not a text file.
   -- a horrible lack of validation and spamminess ensues.
2) Apply patch
3) Create three files.
   a) One containing valid barcodes on each line
      -- this file should trigger no errors. Attempt a valid
         barcode with an umlaut.
   b) A copy of the first with an extra line of >20 characters
      (e.g. The Quick Red Fox Jumped Over The Brown Fence^A^B^C)
      -- this file should trigger the singular error message case.
         ^A^B^C are actually CTRL-A,CTRL-B,CTRL-C, and it is left
         as an exercise to the reader to add them to the line.
   c) A copy of the second with the last line duplicated
      -- this file should trigger the plural error message case.
4) Attempt each of the three files.
5) Run koha-qa tools.

I have a feeling that the column size could be better fetched from
Koha::Database. But it is an improvement in functionality signing off

Works as described, no problems found.
Passes tests and QA script.

Another thing for another day:
Empty lines are counted for the potential barcodes.

Works as expected, tried with arab strings, umlauts and no regressions found.
Bug 4162 - Followup: only count potential barcodes

The $lines_read++; was before the code which skipped empty
lines. By moving it after the next unless $barcode; code, the
$lines_read variable only counts potential barcodes, and does
not include empty lines.

TEST PLAN
---------
1) Apply patch.
2) Attempt a valid barcode file with empty lines.
   -- The potential barcode count should exclude the empty lines.

Empty lines are now no longer counted as potential barcodes.
Passes tests and QA script.

Bug 8539: Library transfer limits page has incorrect permission

Without this patch the library transfer page required the
'borrowers' permission, which is not quite right for a page
in the administration module.

This patch changes the permission to 'parameters_remaining_permissions'

To test:
Verify the page is accessbile with:
- superlibrarian
- administration (full)
- administration, remaining permissions (without manage_circ_rules)
Verify the page is not accessible without all of those permissions.
