Add disconnectOutlet method to controller
Fixed selecting items in ember multi-selects

Worked fine through the API, but when you manually clicked on an option
it would loop around and select the option two in front of it.
Add #setObjects to mutable array. A helper for replacing whole content of the array with a new one.
Small restructuring of ArrayProxy

- For symmetry with other observers, do not
  broadcast content changing events as part of
  initialization.
Improve application readiness framework

- Allow other reasons for deferring readiness
  other than DOMContentLoaded
- Defer app.startRouting until all readiness
  deferrals are complete
- Start app with a single readiness deferral,
  which is advanced by a call to `initialize`.
- If you don't call initialize, you're gonna have
  a bad time.

There are two reasons for this change:

- Allow Ember Data to defer routing until the
  adapter has initialized. For example, an
  IndexedDB adapter needs to establish a
  connection before any queries can be performed.
- Ensure consistent behavior regardless of
  whether DOM is already ready or not when the
  application is loaded. Ensure that readiness
  hooks only run a single time.
