invalid properties get saved

[aheckmann]

var t = new Thing({ thisPropertyIsNotInTheSchema: true });
t.save() // that property gets saved to the db

Contrasting with...

var t = new Thing(); 
t.notInSchema = 'this gets filtered out'; 
t.save()

[aheckmann]

this will have to wait for the next major release since its likely people depend on this behavior

[aheckmann]

resolved in #652

just need docs
