Change didInit event to just init
Factory Injections

Each now uses container.lookupFactory to fetch the correct
'controller:array' factory

container gets factory injections

You are now able to inject on to factories:

```javascript
container.register('model:user', User);
container.register('store:main', Store);
container.register('config:main', Config);

container.factoryInjection('model:user', 'store', 'store:main')

container.injection('model:user', 'config', 'config:main')

container.lookupFactory('model:user').store === instanceof Store;
```

Also the factory returned from `container.lookupFactory` can be used
to instantiate fully injected instances.

```javascript
// assuming the above example

var UserFactory = container.lookupFactory('model:user');

var user = UserFactory.create({ name: 'stefan' })

user.container === container // => true
user.config instanceof Config // => true
```
aliased xProperty methods in enumerable to xBy and aliased some and someProperty to any and anyBy respectively

Fix typos in Ember.Enumerable deprecations
remove 2 year old undocumented behavior
Change behavior around uncached computed properties.

1. Dependent key changes are only observed after
   a computed property has been consumed, and only
   trigger a change event when invalidating the
   cache.

2. Observing a path will not consume uncached
   computed properties.

3. Calling set directly on the computed property
   will still cause a change event (outside of init)
   and set the cache.

This forces CPs to be used as properties rather
than as convoluted way of adding observers to
dependent keys, reduces the event churn caused by
observing paths, and makes unused computed properties
not cost anything.

Example:
```html
<p>{{fullName}}</p>
```

```javascript
fullName: function () {
  return this.get('firstName') + ' ' + this.get('lastName');
}.property('firstName', 'lastName')
```

In this example, sets to `firstName` or `lastName` will
not cause changes to `fullName` until the template is rendered.
After being rendered, only the first set to a dependent key will
cause a change, until the template consumes `fullName` again when
it updates its binding.

Example:
```html
<p>{{authorName}}</p>
```

```javascript
authorName: function () {
  if (this.get('isLoaded')) {
    return this.get('author.name');
  }
}.property('isLoaded', 'author.name')
```

In this example, before this change just observing
`authorName` would consume `author` via the `author.name`
dependent key and after this change `author` will
not be consumed until `isLoaded` is true.

Notes:

If you were scheduling the initial consumption of
a CP via an observer and were not calling this observer
on init but relying on the dependent key set to kick
off initial work, you need to call that observer
on init.

For example, if `selection` is a computed property:

```javascript
selectionDidChange: function () {
  Ember.run.once(this, 'setupSelection');
}.observes('selection'),

setupSelection: function () {
  var selection = this.get('selection');
  // do work with selection
}.on('init')
```

This is good form regardless of it being a computed
property since properties set on `create` do not
trigger observers.
