Image from roi

This PR applies the rendering settings of the source image to the generated images. The problem was highlighted during the workshop in Montpellier

To test:
 * Select an image.
 * Modify the rendering settings e.g. change color so you can remember the changes. Save the rendering settings.
 * Draw a rectangular roi on the image. Save.
 * Run the ```Images_From_ROIs``` on the image.
 * A new image with the rendering settings of the source image should be created.
