Title: Add option to stop calling invalid after first instance of failure

Adds `stopAfterFirstError ` argument to the defaultoptions which is `false` by default, so everything should work exactly the same as it always has by default.

If this option is set to true, the `invalid` method isn't called anymore after the first instance of an error.
This is useful if you only want to show feedback for the first instance of a failure in a form.
