rubygems_deprecate (name, replacement=:none)

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the Rubygems version that it is planned to go away.

        replacement == :none ? " with no replacement" : "; use #{replacement} instead",
