Fix bin/scraper to work with older Term::ReadLine. (Thanks to Tina Müller [RT:29079])
Now link elements like img@src and a@href are automatically converted to absolute URI using the current URI as a base. Only effective when you do $s->scrape(URI) or $s->scrape(\$html, URI)
Added 'HTML' and its alias 'RAW' to get the HTML chunk inside the tag process "script", "code" => 'RAW'; Handy if you want the raw HTML code inside <script> or <style>. (Thanks to charsbar for the suggestion)
