imagesディレクトリの下のディレクトリとしてシンボリックリンクを使えるようにするためのパッチです。
image_finder.rbの
Dir.glob(File.join(@basedir, "**/*.*"))
は、ファイルのシンボリックリンクは辿ってくれるようですが、ディレクトリについては辿ってくれないようです。以下のURLによると、
Dir.glob("**{,/*/**}/*.*")
で解決しそうだったので、コードを変更しテストを追加しました。http://stackoverflow.com/questions/357754/can-i-traverse-symlinked-directories-in-ruby-with-a-glob
