- Refactors some of the old code which was 💩
- Makes SidbarSection a factory for different types of items for the
OutlineView
- Decided not to create a OutlineViewItem.Model class since the only
purpose it would serve would be to validate getters for props or for
documentation, both of which are already done via React.PropTypes.
- Adds sections when looking at unified inbox and integrates with new
mailbox perspecitve interface
- Updates OutlineViewItem a bit + styles
- Tests missing
