Added some logic for parsing enums
Facebook: Improved the documentation of the "FacebookAccount" class a bit
Facebook: Updated the "FacebookUser" class with more properties and property documentation

There are still some properties that I haven't added, but this covers the most basic properties. See more here: https://developers.facebook.com/docs/graph-api/reference/v2.2/user
Facebook: Implemented the "Users" endpoint
Facebook: Implemented the "Albums" endpoint
A little cleanup
