+ Made installer more reluctant to overwrite MS C runtime DLLs -- it's

  been overwriting them even if they have the same version, not just if
  they're an older version (and our installers have always done this).
+ Added an "Advanced Options" subdialog to "Select Components".  Allows
  to do a non-admin install even if you have Administrator rights, and
  to skip registering file extensions and/or creating Start Menu
  shortcuts.  Since so far these installers have been tested only by me,
  and Win2K has been full of surprises, I want those options available
  out in the field.
Lots of web searching turned up what should have been obvious:  Because
Windows Installer is a native Win2K service, it can run at a higher
privilege level than the user invoking it.  So MSI installs don't bash
into these permission gotchas on Win2K, but Wise 8.1 does (it's just
another app to Win2K, and we're not alone in wrestling with this; but,
like changing int division in Python, Win2K is doing a right thing <wink>).
