ftt: allow windowed mode resize options, add title (#646)

## Description of change
This code adds a window title to FutureTomTom when running in windowed
mode and allows the windowed graphics hooks to take effect.

## Testing
I ran the game and made sure fullscreen mode still worked as well as all
window move/resize functionality.
