Delete Image should delete the file

[mtangoo]

Hi,
Thanks for great component. It works great!
However I have found that deleting the Image does not remove the file. It would be great functionality when user does a mistake and want to remove the file and re-generated cropped file.

The Simplest way would be defining another URL for delete where the onclick handler will pass the file name before removing the image in canvas.

Will you accept PR for that?
