Created helpful error message when using @each on an array that does not return objects
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.
Remove unused argument for `Ember.Array#objectAt`

`Ember.Array#objectAt` accepts single argument.
Remove unreferenced property `Ember.Comparable#isComparable`

`Ember.Comparable#isComparable` is not referenced from anywhere.
Fix code comment

`Ember.OUT_OF_RANGE_EXCEPTION` is not defined.
It is exist as a private property `OUT_OF_RANGE_EXCEPTION`.
Example for Ember.computed.alias
Improve assertion for non-Array passed to #each
Improve error message for missing itemView

This commit adds infrastructure for a container to return a
human-readable description for a fullName.

For example, Ember's default container will return App.FooController for
the fullName "controller:foo" (where App is the name of the namespaces).

This paves the way for improving other assertions to describe the
precise name of the class that Ember is looking for, rather than
container keys (which don't match the mental model of an Ember user).

Alternate resolvers should implement lookupDescription(fullName), and
Ember.Application will automatically wire that method up to the
container's `describe` method.
