[TECH-SUPPORT | 2.0.x] AUI-1014 Existing child nodes of the dropNode are not loaded after Drag&Drop. Only dragNode is displayed

Hey Nate,

Here comes the "backport" for https://issues.liferay.com/browse/AUI-1014.
In addition, I'm also sending two other pulls against 1.5.x & 1.0.x to @jonmak08, in order to be able to built & update alloy zips in the affected portal branches.

Regards,
Tibor
