Bug 16933 - Alt-Y not working on "Please confirm checkout" dialogs

This patch changes the keyboard shortcut for renew from Alt+y to Alt+w.

To test:
1) Press Alt+y when you get a "Please confirm checkout" dialog.
2) The renew tab is selected instead of confirming the dialog.
3) Apply the patch and refresh your browser to load the change.
4) Repeat step one.
5) Alt+y confirms the checkout, Alt+w selects the renew tab.
