This adds a new ListItem component and FileUploader component and
updates the Custom settings and scripts page to use this new ListItem
component.
This List component centralises where the markup and styles live. We
still need to update the bootstrap list item and eula upload list item
but will do that in the future.
- [x] Manual QA for all new/changed functionality
