[BUGFIX beta] Remove false attribute from Ember.View

In IE8 (or older), `jQuery.fn.prop` always update DOM against our
expectation.(This is a jQuery bug but it couldn't fix)
ref: http://bugs.jquery.com/ticket/13558

So the following test is failed due to `view.$().attr('foo')` returns `"false"`.:
* https://github.com/emberjs/ember.js/blob/a449d445/packages/ember-views/tests/views/view/attribute_bindings_test.js#L126

To avoid this issue, `removeAttr` should be called when `null`, `undefined` or `false` is given as value.

But this way contains incompatible changes:

Before:
``` javascript
view.set('checked', false);
view.$().prop('checked'); //=> false
```

After:
``` javascript
view.set('checked', false);
view.$().prop('checked'); //=> undefined
```

[DOC][BETA] Improve Em.computed.notEmpty docs to note using array syntax for arrays
[BUGFIX beta] Allow Component to lookup a templateName if specified.

Prior to this change, specifying `templateName` to a component would not
cause that template to be used (since we were overriding the
`Ember.View.template` function with `null`).

This change uses the logic from `Ember.View.template`, which is not
ideal, but I think that these custom docs are pretty important to have.
(They help instruct users that the block passed to a component is
interpreted as its template.)
