Initialize the screen, but not visibly with the setScreen command

[zkarolyi]

Is your feature request related to a problem?

I initialize the menu screen in the Setup section, but by default it shouldn't show the menu, just after button press handled in Loop.
Now after setScreen I hide it, so the screen flashes.

Describe the solution you'd like?

Add optional bool parameter to setScreen as "activate" with true as default value. If I set it to false, the menu does not shows up. Like:

void LcdMenu::setScreen(MenuScreen* screen, bool active = true) {
    LOG(F("LcdMenu::setScreen"));
    this->screen = screen;
    if(active){
      renderer.display->clear();
      this->screen->draw(&renderer);
    }
}
