NSDistributedNotificationCenter: Throw a descriptive exception when gdnc could not be found

Browse source 
`NSTask launchPathForTool: @"gdnc"];` can return `nil` when the tool is not found.  In this case, `[NSTask launchedTaskWithLaunchPath]` would raise a `NSInvalidArgumentException` with error message "NSTask - no launch path set" which is not very descriptive.
