Fixed: if a sheet's parent window frame was changed, the sheet did not reposition

Previously, sheets were only repositioned if the parent window's setFrameOrigin: method was called. This did not cover all possible cases for parent window repositioning.

Now the sheet is repositioned any time the parent window's origin changes.
