Subject: [PATCH] Refactoring of Android's Hackbook example

Summary:
Cleaning of the Hackbook code. Main reason of this commit is mixing tabs and
white spaces inside the code, which makes the code ugly (for example browsing
the code inside github).

In addition I also refactored few other things:
 - I tried to wrap the lines to 100 characters per line (80 per comments) - at
least in those places where it made sense
 - Remove trailing whitespaces and unnecessary blank lines
 - Add missing @Override adnnotations
 - Fixed syntax in some places (like "for(i=0;..." -> "for (i = 0;...")
 - Added missing 'static' keywords

Test Plan:
Run the app and see if everything works :-)
