To get proper entropy in user authentication cookie creation, make use of `SecureRandom` instead of using `Math.random()`, or `Random`. Introduce our own wrapper `SecureRandom` around `java.security.SecureRandom`. This a) makes sure that the PRNG is seeded on creation and not when random bytes are retrieved, and b) uses a static instance in the `UserModel` so that lags do not occur during operation due to potentially seeding getting blocked on Unix when reading from the system's entropy pool. To keep the random data still secure, the static instance will reseed all 24 hours, also a functionality of the wrapper class. This fixes gitblit-org#1063 and extends and closes PR gitblit-org#1116
