Add ability to "delete" or "disable" an application

[rlwakefield]

Working in the cloud, one of the biggest things that can happen is that you want to to no longer allow access to a specific Application. Well, currently the only option is to manually go to IIS and to "Remove" the application and then perform an iisreset. Well, I would like to add a way to "delete" or "disable" an application. I think the disabling would be the better option, but we will see.
