Do not save edited photos as new files

Every time when I use the embedded web app to edit images and click Save button the app it saves them as <filename>_edited.jpg, which is not convenient, as I am looking for the changes in the file I have changed.

I suggest changing the behaviour of how the edited images are saved:

1. When clicking Save button the existing image file is overwritten
2. Add a new button Save as a new file which will prompt the new name for the edited file.

Start by locating the embedded web app's Save action and the code that currently appends _edited to image filenames. Trace how edited images are written and how the save controls are rendered; done means Save overwrites the existing image and a separate Save as a new file action prompts for a filename.
