downgraded for portability. Use getopts not getopt, although it doesn't support long options. Also allow older versions of zip (removed the --quiet option)
Added a further lookup to scrape gallery pages also, not just all-in-one galleries. Also some php-strict cleanup
added docs
fixed up opts after the change from getopt to getopts
Added a bunch of scraping rules. Spidering, spider depth limit, min filesize to keep, renaming rules for target sites that use hashes for hosted filenames. Added scraping rules to support a handful of free image site patterns. fix up to use a subfolder to brevent the archive being a tarbomb. lots of fun.
