Added support for setting error/success classes to any input decorator which contains 'input-decorator' in its class name
Removed the errors popup since it is not really a concern of validator.
Renamed default validations classes to something less generic
Augmented `isValid()` to check also if a control is valid. Also if a form has not been validated will get validated automatically instead of throwing an error.
Added changed event trigger when user presses keys and stops for longer than 1.2 seconds
*Added `optional` validation. *Added clean up of events registered by `addEventListner`, *Validation on `keypress`, *witch of validations
*Added tests
Removed some forgotten code I was experimenting with
