Decoding HTTP error messages

[lxbarth]

Since bones API endpoints error returns are standardized to return a hash containing a message and a status property, should we decode these hashes in Admin.bones' error function?.

Something like:

error: function(model, resp) {
    var message = resp;
    if (resp instanceof Object && resp.responseText) {
        var obj = JSON.parse(resp.responseText);
        if (obj.message) {
            message = obj.message
        }
    }
    new views['AdminGrowl']({
        message: message,
        classes: 'error',
        autoclose: 0
    });
}
