Include numberedmodel and simplesass apps

These apps are so minimal they don't warrant their own repository. I'm
hoping they will find a new home here. This move kind of obsoletes the
github.com/rtts/django-numberedmodel and github.com/rtts/django-simplesass
repositories, although I'm not planning to update their documentation unless
I make any major changes here.
