Various things to make the Finder like us:
 - Change the creator of files we don't want the user to open to 'pTTI' (for
   "PuTTY internal"), and give them application-missing strings.
 - Provide missing-application names for saved sessions.
 - Provide a ResEdit 'TMPL' resource for integers in saved sessions.
 - Provide an icon for saved session stationery pads (maybe "Default Settings"
   should be one of these by default).  No code to handle this yet.
