Joystick button up events was not sent to the EventManager due to a
missing break in the kInputJoystickButtonUp case. This caused button
presses in the launcher and dialogs not to be triggered.
Adding the break enables use of joystick buttons in ScummVM GUIs.
Joystick actions are suitable for joysticks and gamepads where the
movements are updated by a controller stick. On gamepads that's usually
a thumbstick.
Add joystick events which can be triggered by each implemented
controller that should utilize the ScummVM Joystick events.
This is better than using an hardcoded delay for two main reasons.
The first one is that the application can terminate as soon as it
has finished saving the state, and the second one is that it will
still work if saving the state takes longer than the delay that
was hardcoded.
This is necessary for properly identifying the Return key pressed from
the software or a hardware keyboard, and this was erronously removed
in commit e5709ed.
