Created three events for input fields that are fired after validation.

[jmahc]

Created two events that are fired after input field validation/invalidation.

• 'materialize:valid-input' - event is fired when the input field receives the 'valid' CSS class.
• 'materialize:invalid-input' - event is fired when the input field receives the 'invalid' CSS class.
• 'materialize:reset-input' - event is fired when the input field has the 'valid' or 'invalid' CSS classes removed.

These events can be handled with the jQuery on method.

Valid:

$('#inputField').on('materialize:valid-input', function() {
  // handle a valid input field
});

Invalid:

$('#inputField').on('materialize:invalid-input', function() {
  // handle an invalid input field
});

Reset:

$('#inputField').on('materialize:reset-input', function() {
  // handle a reset of the input field
});

Don't think these are that useful as you can do something very similar add a keyup handler and check the input itself or the class we've added
