Bug 9416: (follow-up) fix neworderempty and templates

This followup answer QA remarks :
- neworderempty.pl updated so that the 2 new variables are passed
  to the template
- modordernotes.tt fixed to make the translation easier
- in CSV headers, to make clear that no change are made for the moment,
  rename "note" to "internal note"

Additionnaly, "Publisher code" was wrong in the csv headers. I changed
it to "Publisher" (the field in database is publishercode, but the
content is a real publisher name, not a code)

I did not change "Note:" in modordernotes.tt, because it is just under
a h1 tag which specifies the type of note the librarian is editing.

Test plan :
- edit an existing order, and try to change/add/delete the vendor note,
  and the internal note. Check the changes are properly saved
- export a basket and a basketgroup in CSV. Check the columns headers
  are "Publisher" and "Vendor note"

Fixed some tabs. Passes QA script and tests.

Tested:
- add notes when creating an order
- edit notes modifying an order line
- edit notes using the links on the basket summary
- check basket CSV export
- close basket
- check basket group CSV export
- edit notes on order receive page using the links
- edit notes on receive

Note: Translatability of templates could be improved by a follow-up.
It's better not to divide up sentences with if/else structures.
