changed postToWall() to postWall() in FacebookAuth.java.

created method postToWall(). this method should post without user interaction

in FacebookAuth.java i splite the init() method into two. authorize() and logout(). 

created postToWallDialog() in FacebookAuth.java to display a dialog when posting to wall. 

created a custom exception called SessionNotValidException to be thrown when facebook hates us

t seems the facebook sdk is not saving an access token when trying to make a direct facebook graph request. 
it does save the access token when calling a dialog but prompts for credentials. i believe the authorization process is failing. not sure why. still researching.
