When run with php's build-in server (for instance on localhost:8080), IP provided through $this->server['REMOTE_ADDR'] is [::1], which is not an acceptable format for \inet_pton. This removes the brackets if there's any.

This allows adding rate limiting via annotations to controllers, as one example:
```
@UserRateThrottle(limit=5, period=100)
@AnonRateThrottle(limit=1, period=100)
```
Would mean that logged-in users can access the page 5 times within 100 seconds, and anonymous users 1 time within 100 seconds. If only an AnonRateThrottle is specified that one will also be applied to logged-in users.
