Some setup work

- renamed Index POST to IndexPOST and returning Index(model) on failure
- taking a dependence on the Comments module and flipping CommentsShown on the home page that's created in setup
- redirecting to ~/ on successful setup
- removing the remaining views (home) from Orchard.Web
- updating the slug constraint to cope with a null slug
