Refactor class JoyButtonSlot

[pktiuk]

Class JoyButtonSlot should be divided into several smaller classes with common ancestor.

It would help to avoid mess in code.

New classes should describe actions and execution of them.
It would help avoiding things like:

void sendevent(JoyButtonSlot *slot, bool pressed)
{
    JoyButtonSlot::JoySlotInputAction device = slot->getSlotMode();

    if (device == JoyButtonSlot::JoyKeyboard)
    {
        EventHandlerFactory::getInstance()->handler()->sendKeyboardEvent(slot, pressed);
    } else if (device == JoyButtonSlot::JoyMouseButton)
    {
        EventHandlerFactory::getInstance()->handler()->sendMouseButtonEvent(slot, pressed);
    } else if ((device == JoyButtonSlot::JoyTextEntry) && pressed && !slot->getTextData().isEmpty())
    {
        EventHandlerFactory::getInstance()->handler()->sendTextEntryEvent(slot->getTextData());
    } else if ((device == JoyButtonSlot::JoyExecute) && pressed && !slot->getTextData().isEmpty())
    {
        ///....

Or

if ((tempcode == static_cast<int>(JoyButtonSlot::MouseWheelUp)) ||
            (tempcode == static_cast<int>(JoyButtonSlot::MouseWheelDown)))
        {
            slot->getMouseInterval()->restart();
            wheelVerticalTime.restart();
            currentWheelVerticalEvent = slot;
            getActiveSlotsLocal().append(slot);
            wheelEventVertical();
            currentWheelVerticalEvent = nullptr;
        } else if ((tempcode == static_cast<int>(JoyButtonSlot::MouseWheelLeft)) ||
                   (tempcode == static_cast<int>(JoyButtonSlot::MouseWheelRight)))
        {
            slot->getMouseInterval()->restart();
            wheelHorizontalTime.restart();

Gdybyś kiedyś się nudził to ten task byłby dobry do ogarnięcia.
Przypomniałbyś sobie trochę obiektówki
