Added images to items

Created a new image view to display the images of each item. The user
can use their camera to take a picture of the item. That image is put
in a dictionary and stored with a key to use later when the user wishes
to view that image.

Added Editing and Deleting images

After selecting or using an image, users can now edit their image by
