Update route recognizer
Fix documentation and inconsistent usage for Ember.deprecateFunc()
[FEATURE ember-testing-wait-hooks]

In integration testing, sometimes it's necessary to make `wait` respect
other kinds of pending actions that are not in its default
implementation. For example, if your application is waiting for a CSS3
transition or an IndexDB action, the default `wait` implementaiton will
ignore those things and move on with the test prematurely.

This change lets you register additional functions that `wait` will call
to see whether it's really time to move on.
[FEATURE ember-runtime-sortBy] Adds `sortBy` to the Enumerable mixin.

'sortBy' allows for sorting an enumerable by one the values of one or
more properties.

Update router.js to bc22bb4d59e48d187f8d60db6553d9e157f06789

For didTransition
[FEATURE ember-routing-didTransition-hook] Add a `didTransition` hook to the router.

[Improved assert for #3457] provide helpful assertion if needs is specified but no container is present.
Add `Ember.Subarray.prototype.toString`.

This is mostly helpful in debugging.
[BUGFIX release] `Ember.SubArray` operation composition fix.

In the case where `SubArray` would compose-left, the index was left unchanged,
and we would attempt to compose-right with bad assumptions about what operation
we were composing.
[BUGFIX] Fix an issue with concatenatedProperties.

This commit fixes an issue with how contactedProperties are applied that
can result in subclasses sharing a reference to the same array, in a
surprising way. As an example, the failing test provided here shows
how two Ember.App subclasses shares were sharing inadvertently
sharing initializers.

Thanks to @kselden and @stefanpenner for code review.

Don't allow registration of undefined factories.

container.register(fullName, undefined) now throws
an Exception. This is obviously much stricter then
the current approach, but an obvious win, as we
can detect obviously exceptional scenarios early.
