Dispatch all key and all generic motion events java objects to QtCore

These events are needed to enable the usage of all input methods available
on Android e.g. gamepads, stylus, etc.
In orer to get GenericMotionEvents your application min API version must
be at least 12, otherwise the application will receive only key events.
