created FacebokAuth.java

Browse Source 
created package com.TwentyCodes.android.Facebook in TravelPost. 
moved FacebookAuth.java to package.

created SessionStore.java and SessionEvents.java in Facebook package
created BaseRequestListener.java and BaseDialogListener.java in Facebook package.

modified FacebookAuth.java again. this file will be the object that interfaces with the facebook sdk.
modified FacebookAuth.postToWall(). testing now

added facebook sign in preference to R.xml.settings. currently Travel Post is acting like Your Mom. this should be changed before final testing.

currently app crashes. i don't have enough time to check trace but i sent an email. for now im saving work and will continue tomorrow.
the FC was related to onActivityForResult(). there was a string authcode that needed to be surrended with a null check as its either null or containing data. 
it is null when twitter is not used.

all classes are integrated into Travel Post. as of right now I can post to my wall from Travel Post but it requires user interaction. 
committing work so far and will continue to remove user interaction.

increased build but not version as facebook is not complete yet. build was set to 5 as several changes were made prior this one but the build was not increased
