[Plugin: Visual Form Builder] Validation of secret

The secret question is not validated at all. Put anything in it and it will be allrighty. I’ve tried “hello” and “777” and those validate perfectly well. The only that fails it, is no input at all.

I know, the javascript (which I don’t use) validates it better, but mind you, spambots don’t use javascript.
