Pushed lots of note UI updates to #taproot today, including porting almost all the #js to Backbone. Still #todo:

• Improving location UI: improve cancelled state text, fix located state
• Make a view for note lists, inc. event handling like add new note to the list when it’s posted from the dialog. This will also minimise the number of requests.
• Make the backend auto-add hashtags to the note tags property. It should have been this way all along.
