This patch uses history.replaceState (introduced in HTML5) to manipulate
the browser history to encourage returning to the SCO patron barcode
form if the back button is used.
Note that a side effect of this patch is that if the user uses
the help link, they will be prompted to enter their barcode
again. It may be better to put the help inline with the rest
of the SCO forms.
To test:
[1] Start a web-based self-check session.
[2] Enter a patron barcode.
[3] Allow the self-check session to time out.
[4] Use the back button. You should get the patron barcode
entry form; you should not be prompted to resubmit form input.
[5] Enter a patron barcode, perform some transactions, then
use the finish button.
[6] Next, use the back button. You should get the patron barcode
entry form.
