rework grid layout

Fractional expand is now supported like Qt, and also per row/column
instead of as a widget attribute.

Instead of margins, you're now supposed to use empty rows/columns instead.
Spacer is also gone, use empty rows/columns with minimum size.

Layout engine is prepared to directly calculate edit, button, etc.
sizes without subclassing these controls
