Finder's options methods now set the option when an argument is supplied and returns self for method chaining. When no argument is supplied it returns the option value itself.

Example:

    finder = Redistat::Finder.new
    finder.scope("Foo") #=> Finder object
    finder.scope        #=> Scope object
    finder.scope.to_s   #=> "Foo"
