Propose to delete photos when deleting a product

[CharlesNepote]

What

• When someone deletes a product -- eg. due to vandalism -- the photos are not deleted.
• As a consequence, if the product is created again, the photos come back -- which can be a problem.

Proposed solution

Either:

• a new button allowing to "Delete products and all pictures"
• ask the user when he wants to delete a product: "Would you like to delete photos?"
