[BUG] Handle Reference fields as grid columns

[herflis]

🐜 Bug Report

There's a hard-coded list of field names that are reference fields to handle them as grid columns

export const isReferenceField = (fieldName: string, repo: Repository, schema = 'GenericContent') => {
  const refWhiteList = ['AllowedChildTypes', 'AllRoles']
  const setting = repo.schemas.getSchemaByName(schema).FieldSettings.find((f) => f.Name === fieldName)
  return refWhiteList.indexOf(fieldName) !== -1 || (setting && setting.Type === 'ReferenceFieldSetting') || false
}

It is not okay when you want to work with other reference fields or use them as visible columns in custom drawer item grids

🐜 Describe the bug

👉 Steps To Reproduce

1. Login to snover-service.test.sensenet.com with admin
2. Go to /Content/Tasks
3. Add a new Task with Status: pending and Notified:false
4. open personal-settings
5. Add the following json

{
   "theme": "dark",
   "default": {
      "drawer": {
         "items": [
            {
               "itemType": "CustomContent",
               "settings": {
                  "icon": "AddAlert",
                  "title": "Notify",
                  "appPath": "notify",
                  "root": "/Root/Content/Smartfolders/Notify",
                  "columns": [
                     "RelatedRepository",
                     "TaskType",
                     "Status",
                     "Notified",
                     "Actions"
                  ],
                  "description": "List of accounts that should be notified"
               }
            }
         ]
      }
   }
}

6. Open the newly created menu

😯 Current behavior

[Object, object] is displayed in the reference field's column in the grid

🤔 Expected behavior

A generic logic should be added that displays the referenced content as a link to the content itself. (Later we can discuss about a future feature that makes it possible to configure how this reference field values should be displayed for a specific field)
