Adds spider for picky-palate.com.
Merge branch 'picky-palate-spider' of git://github.com/andbirkebaek/openrecipes into andbirkebaek-picky-palate-spider
convert pickypalate to use Loader & use hrecipe

- I found that newer recipes on this site are using hrecipe. It's not worth pursuing the old ones, which lack any semantics.
