Enhance FileField form field with "delete" checkbox when file is loaded

[Valera_Grishin]

Currently Django displays the FileField and ImageField with file upload HTML widget only. This allows for uploading the new file or image and overwritting already stored file or image with a newer version. But it doesn't give you an option to delete the uploaded file or image. To overcome this problem one must provide a separate CheckboxInput and handle its logic in a view specifically to delete the file.

So, the point is to enhance the FileField and ImageField widgets with checkbox which appear in HTML only when file or image is already loaded. The proposed label for checkbox is "Delete". When checkbox is ticked and new file is not provided the correspoding file (or image) must be deleted on server.

This is a dupe of #7048.

The title of #7048 specifically mentions "admin", thus it isn't immediately obvious that this broader issue is a dupe. It's quite possible the solution envisioned for #7048 will be general and useful/accessible outside of admin, but it would be nice, if that is the case, if that were made more clear. It isn't immediately obvious to me from a brief scan of that ticket.

Karen, I agree that it wasn't immediately obvious, however if you take a look at the patch it does appear that the new Field and Widgets are in the forms dir, so they darn well better be reusable ;).

[Karen Tracey]

Yeah, if you read it closely the solution is for ModelForms in general. I updated the summary to reflect that.

Is something wrong with Track? I only changed the cc, but didn't touch status and resolution. Why those changed too?
