main.cpp rework * Move ClientLauncher class to a dedicated file * ClientLauncher now owns print_video_modes and speed_tests functions (they are only called by him) * Move GameParams to shared/gameparams.h because it's shared between server and client and launcher need to know it * Move InputHandlers class to client/inputhandler.h * Cleanup includes
