bug in FCKTools.GetParentWindow

[Alfonso Martínez de Lizarrondo]

I've run the automated test (first I've had to patch the test files adding a

FCKScriptLoader._FCKeditorPath = document.location.pathname.substring(0,document.location.pathname.lastIndexOf('_test')) ;

so it does work in any directory) and then I've found that Firefox had an error in FCKTools.GetParentWindow I've looked at it and I think that it was wrong because it tries to use document.contentWindow but contentWindow is a property of an iframe, it doesn't point to the parent window of the document in any browser. Instead I've changed to

FCKTools.GetParentWindow = function( document )
{
	return document.parentWindow ? document.parentWindow : document.defaultView ;
}

That should work in IE, Firefox and Opera.

All of these changes are in my development branch
