Merge pull request #2209 from stefanpenner/master

Some minor annoyances.
Normalized Ember.run.later and Ember.run.next behavior.

In particular, callbacks for both are now guaranteed to be run from
within a totally separate run loop; previously, though the docs
suggested so, there was no guarantee the code would be run from
within a run loop at all, much less a separate one.

Ember.run.next is now shorthand for Ember.run.later with
1ms wait, as a result, there was a chunk of `next` code
that could be removed/consolidated in to `later`.

Fixes #913

Added documentation to the append method

I know it's stated on the `rootElement` but I feel re-iterating it here is also helpful.

Fixed typo

extract Ember.isEmpty into ember-metal

Ember computed.empty should always have identical semantics

Also extract Ember.isNone into ember-metal
Ember.isArray implementation lives in ember-metal, its tests should also

Add test of Ember.isArray against an arrayProxy.

Stop using extended method

Because the latter may be undefined.
