* More filling out of parent/child unit tests. * Found a bug in the process. Removing a focused child does not reset the parent's activeDescendant state (it was using child.set("focused", false), which is readOnly. Changed to child.blur(). Fixes #2531907

Filled out line level coverage for Parent/Child selection

Fixed issue where previously rendered children, added to an empty parent, would not get rendered into the parent's child container node. Based on the pull request from andreas-karlsson, with the root fix *and* unit test (nicely done): https://github.com/yui/yui3/pull/25 Fixes #2531093

Added additional check in _uiAddChild, to make sure prev/next sibling is rendered before trying to insert content relative to it. NOTE: This fix is not really required for the out-of-the-box parent/child implementation, but came up because a user had a custom impl. which made child.render() async [probably a valid usecase for parent/child]. See Fixes #2529863

Added unit test for removeChildOnDestroy implementation. NOTE: No code was changed in 3.4.1 for removeChildOnDestroy. Just came across the impl while fixing #2529785, and added the unit test

Use extension destructor support, rather than AOP'ing destructor, which won't work. Fixes #2529785

Prepped tests for coverage reporting

Fixed regression in ParentChild caused by Widget nested UIEvent fixes. Fixes #2530400

Added parentchild tests to smoketests

Fixed WidgetParent remove, to remove child from DOM also. Added tests cases. Fixes #2528911

Changed focusedChild (back) to activeDescendant. Turns activeElement is supported by the A-Grade, and is in the HTML5 spec. Also changing it to descendant, rather than child seemed to make sense as the low-level state, since only one widget actually has real focus. activeChild can be calculated from activeDescendant. See #2528688

Renamed activeItem to focusedChild as per comments in bug report. Fixes #2528688. Also cleaned up some temp sandbox files.
