[reorder] general improvement

[d4rekanguok]

• [x] export a HOC so user can define their own card UI & preview
• [x] handle the case where display fields are out of date // @gurkodil is taking care of this! 💪
• [ ] better looking loading state
• [x] allow item in control to take subfield, i.e ~~fieldDisplay: ['object.field', 'name']~~ display_template: '{{title}} {{categories[0]}}'
• [x] allow users to format fieldDisplay with a template, i.e {{year}}.{{month}}.{{date}} | {{name}}
• [x] handle the case where the targeted folder collection is empty
  • It should ideally also display a link user can click to create a new entry in that collection
• [ ] add options to filter entries by field(s)
  • ~~Is there a way to set this up via CMS.registerWidget instead of config.yml?~~ data config in config.yml, component config in cms.js
• [ ] add a sortBy button in UI. User can select between asc & desc
• [x] allow user to limit the max-height of the control
