Fixed issue with contentBox being left in Y.Node._instances after deep
destroy of an unrendered widget.

This only happened:

1. If using the deep destroy option [widget.destroy(true)] and,
2. If the widget was not rendered.

In this scenario, the contentBox wouldn't sit under the boundingBox,
so boundingBox.empty() didn't have any childNodes to destroy.

When rendered, boundingBox.empty() would take care of the contentBox
just fine. Also for the non-deep scenario, we'd remove(true) both boxes
independently.

Fixed issue with setter not receiving opts, if using AttributeObservable.

The feature to pass `set()` opts through to the setter was added in 3.8.1
but was not working for AttributeObservable (only for AttributeCore).

This fixes it, while trying to keep things tight for the 80% no-opts case.

The use of the `fire(type, facade, opts)` signature may have a perf impact
on the 20% opts case, but it keeps the 80% path tight. Other options
required us to add additional `if (e._attrOpts)` type checks to the 80%
path to keep things clean.

We can extend the optimization in custom event for this signature if it
bubbles up as a perf issue.

Removed uploader-deprecated from build dir.
