[Plugin: Custom Contact Forms] Can't change label on captcha field

The captcha field shows numbers, not text; and so the label “Type the text” is a bit misleading. But you can’t change the label on the captcha field. No matter what you enter on the setup form, it still shows “Type the text” on the live page or widget. It’s a small thing but it matters.
