updated to newer scotty version and a site skeleton

Hi, I updated this to remove the deprecated calls to `settingsHost` and `settingsPort` and included all needed dependencies so that sandboxing should all right.

In addition I think it's a good idea to give some kind of scotty skeleton to serve some common static files (two html sites, one css file and favicon.ico - I shamelessly stole this from the openshift site ... hope they don't mind).
On top I gave a server-site function to demonstrate how to get parameters from calls using scotty - this should be all a beginner needs to get up some nice website.
