core (client): component improvments: - renamed component boolean to is_component for more clarity - profileConnected/profileDisconnected don't use a suffix anymore, it's called for both client and component. To check for there, the is_component boolean is enough - fixed dependencies handling - componentStart is not mandatory anymore, as a component can just be used with its handler
