Features & bugfixes

- Feature: added new getFirstHeader to Request object that will return the first header found from array list- used to simplify the code.
- Feature: added new InputHandler::getValueFromArray method that loops through input-items to ensure that value is always returned.
- Fixed calling getUrl with array as parameters option throws error.
- Fixed `SimpleRouter::getUrl` having wrong nullable return type.
