- 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
Partial cleanup of piskel:
new events and constant
move palette and color picker in ToolSelector
create Notifcation.js and move user message in it
create LocalStorageService and move LS stuff in it
