New sortable_columns option in metadata.json to control sort options

Browse source 
You can now explicitly set which columns in a table can be used for sorting
using the _sort and _sort_desc arguments using metadata.json:

    {
        "databases": {
            "database1": {
                "tables": {
                    "example_table": {
                        "sortable_columns": [
                            "height",
                            "weight"
                        ]
                    }
                }
            }
        }
    }
