rooFacebook2 is Facebook extension for Marmalade SDK

It differs from original s3eFacebook

1. It stores access_token (User do not have to login manually every time app is launched)
2. You can set access_token manually
3. Parameters are passed as JSON (So you have to make 1 call instead of 3-4 calls)
4. Supports more FB functions like extendAccessTokenIfNeeded, etc
5. SSO support on Android. To implement it you have to re-compile android loader for and add small portion of code. Hopefully Marmalade team will open source loader or will add similar functionality. I have implemented custom activity instead.
6. rooFacebook2 is early and buggy. It may have memory leaks on iOS (release could be missing somewhere)
