    settings: install some reasonable defaults for common languages
    
    If ~/.local/share/gnome-builder/.defaults-installed is not found, we
    will set some reasonable defaults for C, Python, Ruby, JavaScript, XML,
    etc.
    
    We will likely iterate on these defaults a bit. Especially with how they
    will tie into auto-indentation in the future.
