Panel: Save applet position before deleting

Before marking an applet as deleted, save its container position to
the applet item position itself. when adding it back, if the passed
position to appletAdded is <= 0 , use the applet positions which
if is an "undo delete" was set at marking the deletion, it will have
the old position to restore.

Save the position of the container on an applet attached property before
container removal
