Relocated todo_controller#deferred_update_action to be next to todo_controller#update_action
Include all non-hidden contexts on the home page, but hide the empty ones. Ground work for supporting the automatic showing of a context with zero items when an item is moved to it.
Added a comment about todo_controller#update_element -- is it used?
Remove unused #list_of method from context, note & project models
Remove unused #list_all method from note model
Methods to lazy load done_todos and not_done_todos for project and context models

It has these features:
* The todos table and model has been altered (run rake migrate to update) to create two sub-classes of the todo model: Immediate and Deferred. Fairly obviously, Immediate actions are those shown immediately, and Deferred are those shown when certain conditions are fulfilled. At the moment, this is when the 'show_from' date arrives.
* Deferred actions are created on a separate page: /todo/tickler. You can view the show_from date here and delete or edit the actions. Deferred actions don't show on the home page (their handling on project and context pages is still to be fixed).
* A periodically called method (every 10 minutes) checks whether any of the deferred actions is due to be show, and if so, a warning message is shown on the home page to tell you how many deferred actions are to be shown. You need to refresh the page to see them (again, this is to be fixed).
* When deferred actions become due, their type is changed from "Deferred" to "Immediate". The handling of their staleness is still to be fixed.
There's a way to go before it's really smooth, but it's a start.
At least partially fixes#270 and #78, but will be improved with time too.
