Shortcut never activated in Qt6

[RomainCendre]

Hi dear team, I made some test on Qt6 and it seems that you cannot get an active shortcut anymore =/ I don't know if the nativeevent function is responsible from this behaviour. Anyway thanks for providing this usefull tool!

Change in file uglobalhotkeys.h and uglobalhotkeys.cpp the signature for the function bool nativeEvent(const QByteArray &eventType, void *message, long *result) into bool nativeEvent(const QByteArray &eventType, void *message, qintptr *result) and the hotkeys will work also for Qt 6
