Minor security update

The website was updated today.

Just a minor security update to prevent hackers from trying to guess app IDs, or at least make them go away.

1. Please do not hack this website
2. You can create a new account for free and get your own free app ID
3. Our app IDs are 64 bit longs, so your chance of guessing a valid app ID is about 1 in 18,446,744,073,709,551,616. So if you made 1,000 attempts per second, it would take you about 584,942,417 years to guess a valid ID...
4. We now automatically ban IP addresses that make 10 invalid app ID web API calls (for 24 hours)
