v0.0.6

• Improve UX: previously, if you submitted a form with an error like "Input is required", the error message used to stick to the field until you focused out, which was a bit bad from a UX point of view. Now, once a field has been validated once, we attach the validation also on keyup event, so that error message is gone as soon as possible. The reason I don't attach the listener directly on keyup is that because on initial typing, having the error message showing as you type is a bit annoying (especially on fields like "email").
