Image gallery

[sweco-segilr]

Images in the "Current folder" would be nice if they could be viewed as a gallery as a new tab in Kids Ruby. With the current features:

• Drag-n-Drop images to the gallery.
• Delete images
• Double-klick the image to add path to the image to the current code window.

Adding images to the program is one of the first things any kid would like to do. But to figure out where to save the image and how to write "Project X/Image Y.png" path is hard. The stack-trace when the path is wrong is not helpful to a beginner.
