Bug 16914: Rely on TT for newlines

The translation scripts have an historical tendency to chomp newlines
and we introduced an empty_line.inc file to force newlines when building
CSV output out of our templates (in item search and late orders).

This patch makes the mentioned templates use TT ability to force newlines
plus some misuses of the 'minus' sign.

Test plan:
- Apply the patch
- Do an item search that returns more than one result
- Export as CSV
=> SUCCESS: The CSV file is correctly formed.
- Install any translation:
  $ sudo koha-shell kohadev
 k$ cd kohaclone/misc/translator
 k$ perl translate install <chosen language>
- Enable <chosen language> (e.g. es-ES)
- Repeat the item search
- Export as CSV
=> SUCCESS: The CSV file is correctly formed in your chosen language.
- Have more than one late orders (bummer)
- Go to late orders
- Choose them
- Export as CSV (in english)
=> SUCCESS: The CSV file is correctly formed.
- Switch language
- Go to late orders
- Choose them
- Export as CSV (in english)
=> SUCCESS: The CSV file is correctly formed in your chosen language.
- Sign off :-D
