A tidier frame menu, with Generate and Refine on the canvas

The frame menu is now grouped into adding an image, the image itself and the frame. Empty frames show Generate image on the canvas, and frames with an image show Refine image.

• Upload image opens your computer's file dialog.
• Dropbox and Google Drive sit together under More sources….
• Comment opens the comment box on the frame.
• Delete frame sits on its own at the bottom and asks you to confirm.
