Resolved implicit conversion.

`SCNetworkReachabilityGetFlags()` returns a `Boolean`, not `BOOL`. This can cause a warning/error depending on your compiler flags. As this was only used once in a conditional expression, maintaining the `Boolean` throughout should be fine.
Suppressed deprecated implementation warnings.

Depending on your compiler flags, these deprecated method implementations may cause a warning/error. While you can disable this on a per project or per file basis, using `pragma` is a more universal solution.
