Commented Feature: Implement : [lists/subscriptions] [1759]

Reference : https://dev.twitter.com/docs/api/1.1/get/lists/subscriptions

Parameters :
- user_id
- screen_name
- count
- cursor
Comments: Associated with changeset 44228: Version 0.9.8.0
- Removed the old version of GetSubscribedLists (https://dev.twitter.com/rest/reference/get/lists/list) because it only returned the first 100 TwitterLists and returned both Owned and Subscribed lists. This function will still be available to developers using the TwitterListController.

TwitterList.TwitterListController.GetUserSubscribedLists(, true);
