Bug 12111: Improving templates regarding order notes

This bug changes some lines in modordernotes.tt to make them more easily
translatable, especially in german (remark by K. Fisher on bug 9416).
No change should be visible

It also suppresses the ability to edit order "vendor note" in reception,
as the note for vendor is not made to be changed after the document is
received.

Test plan :
- in a basket, try to edit the notes (internal and vendor) of order.
  Check the display is correct
- go in reception module (parcel.pl page) : in the list of all orders
  to receive, you should have a link to change "internal note", but no
  more link to change "vendor note"
- try to receive a specific order which have a "vendor note". On the
  right panel of the page, you must have an editable textarea for
  internal note, and a non-editable (colored in grey) textarea for
  vendor note

Bug 12111: (follow-up) fix breadcrumbs wording for vendor note

As asked by QAer,
this followup fixes wording in modordernotes.tt for vendor note
(Change order vendor note vendor note => Change order vendor note)
It also uses [%- and -%] to make code more readable

Test plan :
try to edit a vendor note, check the wording is correct in breadcrumbs

Bug 12111: (follow-up) ensure that vendor note is not editable during order receiving

This patch removes the ability of finishreceive.pl to change the vendor
note of an order.  It also uses a normal span rather than a disabled
textarea to display the vendor note on the receiving page, to emphasize
that it cannot be changed.
