lobby_menu.cpp builds, as does all of client/menu_scenes

This is great progress, but I think I should turn the common directory into a subnmodule, since
I've been constantly tabbing back and forward between this folder, and the debug folder, making
and committing identical edits to both.

 Scene list:
        > disconnected_screen.*pp
        > lobby_menu.*pp
        > main_menu.*pp
        > options_menu.*pp
        > splash_screen.*pp
        * world*.*pp

        * unfinished
