Fixed image distortion on thumbnails
Web page thumbnails are no longer distorted to fit the frame and instead fill
the entire width and are cropped when they go past the height
Switched from dragsort to jqueryui dragsort method
The library caused odd errors of dragging internal divs to each entry. New
method is more customizable and works properly. One feature of customization
that was added is a deadzone where if the mouse moves less then 20 pixels.
