Protects forms to be submitted twice

Vanilla JS form submit once protection

Forms usually need to be submitted once., _(*1)

When double submission does occur (i.e. because of double clicking), unwanted side effect can occur: * duplication of records in a database * multiple actions such as i.e. sending duplicate emails * thrown exceptions as systems could not expect certain actions to be executed twice, _(*2)

This "Js-SubmitOnce" script is a plain JS vanilla script to prevent this undesired behavior., _(*3)
