Added ActionBarSherlock, Navigation Drawer, Integrated Index application, Implemented gmail login

Converted required activities to fragments for better integration of Navigation Drawer.
Moved old Home screen menu to Navigation Drawer. 
Index application is the new default screen after login. 
Gmail login uses oauth2 token obtained using google play services.
Additional external dependencies:
1. ActionBarSherlock
2. Google Play Services
As far as I understand, a switch case will have an exhaustive list of possible cases. 
Right now, the statement 

    if (position >= 2 && position < 2 + createList.size())
would work for any number of Privly Applications as I am passing the JsAppName variable to the NewPost fragment. Going for a switch case would require writing explicit code for each case.
