LPS-50453 - https://issues.liferay.com/browse/LPS-50453

Hi Rob,

Attached is an update for https://issues.liferay.com/browse/LPS-50453.

In 80d8eaa, I converted the use of of the alloy-io plugin into the jQuery.load() method.  It works great, but unfortunately it doesn't have a loading-mask feature like alloy did.  So we may want to leave that commit off, but I wanted to see what you thought about it.  I think we may have to use another jQuery plugin for a loading mask, or create our own.

There are a couple places in this portlet I left still using aui-base as it is in tags with liferay-upload and liferay-export-import.

Please let me know if there are any issues.

Thanks
