Swap positions of "Back" and "Enter" buttons in PSPSaveDialog.
Make the default choice in all save dialogs except for overwrite/delete confirmation be "Yes".
Always pick up the saveID by latest file time instead of the previously used one.
This fixes SRWAP & SRWMXP.
Support more list focus settings.
