!! NOT STABLE !!
Initial implementation. No UI update yet.
Check js/model/Piskel.js and js/model/Layer.js for an overview of the new
API.
Piskels can be saved on the existing service.
Previous piskels cannot be loaded. This should be fixed soon.
- Updating DnD to use Sortable instead of draggable/dropppable
(updating deps as well).
- much simpler logic for DnD
- Remove LESS for now since it's a bit yet overkill
- fix moveFrame function
