webui-css: improve radio,checkbox keyboard support and color

checkboxes and radio buttons:
- do not change color on hover when disabled
- are focusable and checkable be keyboard again. This uses a little
  trick where the real checkbox is hidden under the artificial
  checkbox. That way it has the same position and therefore it
  works even in containers with overflow set.
