Progress window is modal #fixed

[Tantalon]

Changes:

• Fix for window losing focus introduced a regression - the progress window is no longer modal. This is because setIsVisible:false has the side-effect of disassociating the window from its parent. This pull request fixes it in a different way - replace removeChildWindow with orderOut. This stops Sequel-Ace from losing focus, while retaining the parent relationship and the modal behavior.

Closes following issues:

• Closes: The Running query modal window is not modal anymore #1879
