1.0.3

• New: Themes and plugins can register their own form skins with the streamery-forms/skins filter, including skins that extend another skin.
• New: Checkbox and radio options can show an image (top left on the Cards style).
• New: Checkbox and radio groups can offer a custom option where visitors type their own answer.
• New: "Hide label" toggle in the global field settings. The label stays available to screen readers.
