Pinger supplies a tokenized URL to WebClient

[bherila]

As part of the Scheduling/KeepAlive, Pinger.cs supplies a tokenized URL to a WebClient without first parsing it.
src/Mvc/MvcTemplates/N2/Resources/KeepAlive/Pinger.cs line 42.

 string response = wc.DownloadString(url);

Should be.

 string response = wc.DownloadString(Url.ParseTokenized(url));

This is taken care of by url = url.SetPath(config.Scheduler.KeepAlivePath.ResolveUrlTokens());

The extension methods in ResolveUrlTokens parse the tokens in question.
