Cleared console.logs in the Orchestrator
Integrate sorting into validateTree, Ticket0656
Since otherwise, validation might fail
Removed any save/destroy call from a branch, Ticket0656
This will allow me to keep everything in memory and save all at once at the right moment.
Refactored validation and processing to server, Ticket0656
Only Transporter deals with storage and server
Validation is made against allNotesByDepth
* Remaining issues
  - Syncing can be interrupted in the middle of processing to server
  - Dealing only with localStorage makes it difficult to isolate new changes from validated ones
