New feature to listen keyboard events

Thanks to @hashmatmuqbil . I introduced a feature so the button will always be visible when the keyboard will appear.

The main component now have two new properties:

• listenKeyboard will enable the keyboard listeners to move up and down when the keyboard appear and hide
• dismissKeyboardOnPress this property is related to listenKeyboard, now the user have the possibility to hide the keyboard when the user click the main button. This is because sometimes we have a big a list of actions and listenKeyboard could ended up showing actions outside the screen.
