Option to remove the profile picture or a Delete button

In Confluence our users doesn't have an option to remove the profile picture, or a function to return to the default one(when you don't have a profile picture).

Our customer asked some instructions of how to remove the profile picture since it doesn't have anything in the User Interface. The only way that we found was through the database by removing an row from the os_propertyentry table and a script created by another customer in the Atlassian Answer.

Confluence should have a "Delete" button as the 5.1.5 version has.

Steps to reproduce:

1. Go to your Profile page.
2. Upload an image.
3. Try to delete without uploading a new one.
