* Creates the BUILD_SURF build option
* Managing starting with no game loaded
When built with BUILD_EDITORS=OFF, and we execute the app without any
game, it starts by showing the Main menu.
We also hide options from the menu when there is no cart loaded: the
Resume and Reset.
When we start with no cart and we try to do a Surf, it was saying there
were changes made to the cart, so I also do a check if the cart was
loaded before showing the warning.
So, basically when the App is started without any games, it will show
the options: Surf, Options, Quit
* Android: BUILD_EDITORS=OFF & BUILD_SURF=ON
* Fix inisializing cart by arg when BUILD_EDITORS=OFF
