[Koha] Web Circulation

[Tonnesen Steve]

Finished up a few more items, found some more missing parts:

  Returns module lists recently returned items
  Cookies used to store branch and printer choices
  Link allows you to change branch and printer choices
  Entering invalid barcode in issues or returns results in an appropriate
    error message
  Prettier output when a book is "returned" that wasn't loaned out
  

Still to be done:

1.  Prettier graphics.  Rachel at Katipo says she'll take of this.  :)

2.  Reserves are horribly messed up.  Reserves aren't updated when the
    book is returned, and reserve notifications are not shown in the
    patron info box when books are issued or returned. 

3.  Overdue fines are almost certainly not being set.

4.  Should list the patron who returned a book in the returned books list,
    and the due date (highlighted if overdue).
