- Created a generic social media session manager which now serves as a manager of all service login statuses, and performs delegation of all posting to the appropriate services
- Implemented a new interface which allows for posting to either Facebook or Twitter, as well as to both at the same time
- Created model objects to hold generic Sharable and Story types which can be used to store the superset of information necessary to post to all services being managed by the meta-manager
- Fixed a retain-cycle issue which existed in the callback functions used in the Facebook posting method
