Muhammad Rifqi Priyo Susanto 792752997c Add confirmation on new player registration (#6849)
* Attempt to add registration confirmation

Using SRP auth mechanism, if server sent AUTH_MECHANISM_FIRST_SRP that means the player isn't exist.
Also tell player about the server and chosen username.
Local game has localhost as IP address of the server.
Add RenderingEngine::draw_menu_scene() to draw GUI and clouds background.
aborted -> connection_aborted

* Rewrite information message text

Client::promptConfirmRegister() -> Client::promptConfirmRegistration()
