Use Trash icon for delete buttons

Problem/Motivation

The size of the delete button in file / image forms seems to require a no-wrap css...

Additionally - how about making the button red and pefix with a Trash icon? A checkbox seems wronf to me if I delete something.

Steps to reproduce

Proposed resolution

Use https://icons.getbootstrap.com/icons/trash/ icon and make the button "red".

Remaining tasks

User interface changes

API changes

Data model changes
