Title: Remove dead code from Guest

While thinking about host capabilities stuff and looking around the codebase I found those guys which I believe have all been converted to guest capabilities. Some "grep"ping showed me no references to them so unless there is a chance that they are possible in use by third party plugins I think it is safe to remove them by now ;)
