currently working on v0.3
WIP drag & drop item in the list to move them
- currently not sorted
- currently not synced with the server
WIP drag&drop: insert element directly in the right place
also disable it for children of source item
WIP drag&drop: make the server call for syncing
WIP drag&drop: save new location of item on server
added fallback: display notebook root when note/directory not found
FIX avoid moving item into the same directory (would accidentaly delete it from json)
FIX couldn't drop on selected directory
 + avoid unecessary server call if dropped on its own directory
FIX update data-path to (sub-)item after they were moved
drag&drop: ability to drop on the root (notebook title)
added hover effect on dragging items over other items + reorganised javascript for drag&drop
only dragover & drop on directories (and remove .hover after drop)
when dragging, darken the panel to highlight the droppable zones
FIX dra&drop: missing or unnecessary '/' when regenerating path to moved item
FIX always update 'updated' date in notebook when changing it
FIX upadate item in every descendant link of a moved item
FIX always keep the right path to item for saveNote() even after the item (or its ancestor) was moved
Merge remote-tracking branch 'github/master'
updated toto and version history
