Implicit where has with where method.

[josephmancuso]

I saw this syntax in a PHP package and love it:

$posts =
    Post::where('author.name', 'John')
        ->take(10)
        ->get();

This is the same as:

User.where_has('author', lambda q: q.where('name', 'John'))

I feel like we can easily detect a dot notation in the where method and explode it out to a wherehas

we just have to watch because i think we use this syntax already for tables? will have to check
