add Ember.computed.defaultTo
A small change to make the assertion raised when Handlebars isn't found more clear about how to fix the problem
Actions should be unregistered when destroying virtual views
fallback for browsers that don't support domElement.outerHTML

At least Firefox browsers < version 11 do not support the outerHTML
property for DOM elements. The fallback is to use
XMLSerializer.serializeToString when outerHTML is not available.
Avoid parent's implicit index route clobbering child's explicit index.

Fixes emberjs/ember.js#2318.

Make {{partial}} and {{template}} helpers lookup templates using templateForName

This commit changes the implementation of the `{{partial}}` and `{{template}}` helpers to lookup templates using the view's `templateForName` method, like other template lookups, rather than directly from `Ember.TEMPLATES`. This will make it play nicely with container-registered templates. Fixes #2295
