Merge pull request #1 from davesnowdon/master

Dumb fix to code storing triples
got some unit tests working on the faqbot query method
merging in Dave's persistence with my new units tests for faqbot
unit tests I don't remember adding ...
merging those old tests - which were the prompt to fork naturaljs and put the tests there
throwing out remnants of those old tests as they were superceded by using Xregexp
some merge junk left in faq.html - not sure why I wasn't finding it in project search
lost a library
got stopwords working, not sure how to query rdf databank
see more of unit tests on faq page
