Posted when network reachability changes.
The notification object is an `NSNumber` object containing the boolean value for the current network reachability.
This notification contains no information in the `userInfo` dictionary.
@warning In order for network reachability to be monitored, include the `SystemConfiguration` framework in the active target's "Link Binary With Library" build phase, and add `#import <SystemConfiguration/SystemConfiguration.h>` to the header prefix of the project (Prefix.pch).
