Let me use interface{} for template vars

Browse Source 
Since most of the `render.Vars{}` fields were hardcoded/not really
editable for the templates, apart from .Data, this struct is now locked
away in the render subpackage.

End http.HandlerFunc's can then make any arbitrary template data
structure they want to, available inside the templates as `.Data`.
