V9.4: does fades, reads links and more Exif

The big news is that a dissolve feature is now available in release 9.4. This required a major rewrite and efficiency review, since 2 images are being rendered with varying opacity 10 times a second during the fade, instead of one every 4 or more seconds.

PicShow supports shortcuts to image files now.

And I deleted my Exif-data-reader class when I moved to VB 2010; instead I use built-in methods and select one of these:

• 270, x'010E - Image title/description; ASCII; highest priority
• 40092, x'9C9C - Windows Explorer comment
• 37510, x'9286 - Exif UserComment: ASCII, Unicode, other, but delivered to user as Unicode regardless; lowest priority

The folder-selection process (if PicShow is not called with command-line arguments) uses the newer folder dialog box rather than the VB 6 controls.
