Added Wifi based securit ratings to system security
Reworked SecurityRating
Added reasons to SystemSecurity

MainActivity is now ApplicationRatingsActivity
The new MainActivity is now the interface for system security

Added Drawer functionality for navigation. Use the top left icon for
navigation. (back button functionality needs to be rethought here)

Fixed bug were all applications were listed twice.

Fixed bug where applications not on google play would be rated by
downloads and not by rating, now its by neither.

Needs some serious cleanup and JavaDoc to be added, the code that I
wrote here was written quickly, needs JavaDoc badly.

Renamed stars to ratings for Applications
