Bug 10376: fix ability to print cart from IE9 & 10

Test plan:
1) Test with Firefox (or any other browser except IE):
Add biblio to cart
Go to Cart and click Print
Does the Cart window come back to its original state after confirm/cancel Print?
2) Test with Internet Explorer (I used IE9; testing another version is fine)
Do the same as above. Is behavior now more or less the same?

1) Test without patch:
IE 10: Does not show print dialog
IE 9 (Developer Emulation in IE 10): Does not show print dialog (as expected)
FF 21.0 OK
Chrome 27.0.1453.110 m: OK

2) Test with patch:
IE 10: OK
IE 9 (Developer Emulation in IE 10): OK
IE 8 (Developer Emulation in IE 10): OK
IE 7 (Developer Emulation in IE 10): OK
FF 21.0 OK
Chrome 27.0.1453.110 m: OK

Trusting Marc here, as I don't have IE available.
Regression tests in Firefox and Chromium went well.
