Don't auto-scroll list of images

[forteller]

When you open Fotema after having added more photos to your folder, the list of photos are updated twice: First just to add placeholders, then again after miniature images have been created.

On these updates you're automatically scrolled down to the bottom of the list of images if you've started scrolling up. This is annoying when you've started looking for something and have to start again. Hope this can be fixed. Thank you! :)
