Notepad: Changes to the Page setup dialog

The attached patch makes the following changes to notepad:

• Raplace the page setup dialog with a modified copy from comdlg32. Use PageSetupDlg and a hook
  function to bring the dialog on screen instead of DialogBox and a dialog procedure. With this,
  PageSetupDlg can do most of the work (init the controls for example).
• Save the returned hDevMode and hDevNames to two global variables, so we can use them in later
  calls to page setup and print.
• Include header, footer and page margins when saving/loading settings.
• Remove printer setup from the file menu (and related code/resources) since it isn't needed anymore.
