Add dir? to file

[joseramonc]

I can't differentiate easily between Dropbox::API::Dir and Dropbox::API::File, I'm interested in differentiate to put a different icon in the view, I'd like something like this.

@client.ls.each do |file|
  if file.dir?
    puts 'directory-icon' 
  else
    puts 'file-icon'
  end
end

I can work on this if it's a feature you'd like to add.

I guess it's a nice-to-have, considering the alternative .is_a? Dropbox::API::Dir is just a little verbose. I think just adding class Dropbox::API::Objet; def dir?; is_a? Dropbox::API::Dir; end; end would do the trick
