- Updated all dropdown list item actions into three specific styles:
icon-item, text-item & label-item. Allows a stronger structure while
prevents mixing of styles as we were getting for header dropdown in
dark mode.
- Extracted out page editor top toolbar to its own view file & split
editor switch options to different markdown options.
Cannot get working in chrome reliably due to conflicting handling of
events and drag+drop API. Getting attachment drop working breaks other
parts of TinyMCE.
Implementing current work as should still work for MD editor and within
FireFox.

Currently fighting between sortable and tinymce mechanisms which prevent
this working due to the different events stopping the drop event while
needing the dragover for cursor placement.
