Redesign startup activity, user account creation, add incognito setup

Everything works for me (tm)

New design:
On Antox startup, StartActivity is now called, and detects whether or not someone is currently logged in (setup). If not, it fires CreateAccountActivity, and if so, it continues and launches MainActivity.
