optimized the snowflake id generation for loops.video*:

```
return ((round(microtime(true) * 1000) - 1711000000000) << 22) | (random_int(1,31) << 17) | (random_int(1,31) << 12) | 0;

```

* - the 0 is really a redis counter, but works for this example. This works great for single servers, but we'll have to tweak once we need to scale up (and replace the random_int() with dc/worker ids)
