Add support for $ref on properties

[shmax]

Adds support for $ref on the properties attribute. You don't often see examples of this kind of thing out there in the wild, but $ref is actually not defined by the json schema standard; it's more of a JSON thing , and it's very useful in situations where you want to make properties of something reusable while still controlling a custom description or name:

$schema = [
   "frontPhoto"=>[
       "type"=>"object",
       "description" => "Supply a nice photo of the front of the object you want to sell",
       "properties" => [
          '$ref' => '/path/to/photo.attributes.json'
       ]
   ],
  "backPhoto"=>[
       "type"=>"object",
       "description" => "See if you have a nice photo of the back of the object you want to sell. This photo is optional",
       "properties" => [
          '$ref' => '/path/to/photo.attributes.json'
       ]
   ]
];
