size option buttons to the face they carry

QPushButton derives its size hint from its text and icon and ignores a
layout set on it, so the recipe options, the shipyard schematic options and
the layout dialog's module buttons all measured themselves as empty and
clipped the name and recipe line drawn on them.

OptionButton takes the hint from its layout instead and lets the style add
what the button frame needs, so the padding stays the platform's rather
than a number picked here. It falls back to QPushButton's own hint when
there is no layout, which is what the "(None)" option uses. The module
buttons drop their fixed height with it and take what their cost line
needs.
