massive UI overhaul:

- user interface can now be toggled between
   - **split view**: classic ChanSort UI with new/ordered and old/full list side-by-side
   - **single-table**: simplified and more intuitive UI, but not quite as powerful
  When you choose to "Modify current list", the single-table view is used by default,
  otherwise the split view. But you can always toggle between them.
- added option to select a color theme. The UI now uses the "Office 2019 Colorful" theme by default,
  the old theme was "Office 2016 Blue".
- improved many keyboard shortcuts (open the drop-down menus to see the shortcuts)
- improved some icons to work better with dark themes
