Fix chrome additions and remove 'L.addNote'
Add default to _.pop
Comment and cleanup.
Better note helpers.
Don't use events to trigger actions.
Bind more action queue methods.
Add chunking method to underscore extensions.
Don't pass back attributes on update

Prevent change from being triggered on save.
Add note id to note elements.
Raise event on link open from note.
Revamp search procedure

Instead of searching ondemand, simply render ondemand. Searching is
still asynchronous but the enter search is performed and only visible
(plus a few extra) notes are rendered.

This allows for two features:
 1. The scroll bar is the right height.
 2. The results exist and can be logged.
