Update jQuery files

Demo theme: v1.10.2 -> v1.11.1

Extend query on relation behavior

From a relation behavior config file like this

status:
     label: Status
     list: @/plugins/path/to/your/relation/config/columns.yaml

{
     if ($field == 'status') $query->where('thing', '=', $this->thing);
}
