Merge pull request #4346 from rjackson/update-ember-dev

Update ember-dev to ensure transpile is done during dist.
Starting to put together the pieces...
Spike on a simple view class
Define parentView in the prototype
Few tweaks for extra perfs
This view class is like a finely tuned Italian car
Minor tweaks for building
Spike on each helper
Created a SimpleObservableArrayMixin for use with ArrayObserverStream
Update HTMLBars. It's failing tests. Committing for Kris to see.
Pass options.data through
More work on the each helper. Need to do some more work on Range before I can get this test passing.
Define META_KEY on the prototype so we're not changing the shape of the object on instances
Update htmlbars and bound-templates.js. Rearrange code.

The "Ember.HTMLBars: #each" test is failing.
A slew of experimental tweaks to meta and chains.
Update bound-templates.js, misc. perf tweaks, and significantly reduce garbage being created.
