Created helpful error message when using @each on an array that does not return objects
upgrade RSVP
Deprecate `template` in favor of `partial`

Also, don't emit a warning if you use the de-underscored
template name with the `partial` helper.

This is a step in the direction if simplifying all the
different ways to insert a template.
Improve `Ember.inspect` for array
Add 'date', 'regexp' and 'error' supprot to `Ember.inspect`
Support object with `Ember.String.fmt`

* before:

``` javascript
'data: %@'.fmt({id: 3}); //=> 'data: [object Object]'
```

* after:

``` javascript
'data: %@'.fmt({id: 3}); //=> 'data: {a: 1}'
```

This commit improves assertion message such as the following:

``` javascript
Ember.assert('Your data must contain `id`. But actual: %@'.fmt(data), data.id);
```
