Bug 7166: Adds edit order notes when the basket is closed

Bug 7166: Adds edit order notes when the basket is closed

 When you are on parcel.pl or basket.pl you can now add or edit a note
 for each order.

 To test:
 Create orders with and without note.
 Edit/Add the note on basket.pl page

 Close the basket.
 Check you can add/edit the order note on parcel.pl page

+ From Owen:
Correcting markup issues with modordernotes.pl:

- Adding "rows" and "cols" attributes to <textarea> (required)
- Converting cancel button to link to stay consistent with
  other pages
- Changing page layout to fixed & centered (not sidebar needed)
- Expanding information in breadcrumbs to match information
  on basket.pl

Changing markup around note add and edit links: Moving output
of order note to the end of the table cell, putting it in its
own paragraph, and adding a "Note:" label
