Fixed issue with Russian language text processing.

Fixed issue #2.  There was a problem converting the JSON objects for
the post to AlchemyAPI.  JSON.stringify caused Russian and probably
other languages text to not be properly encoded and return incorrect
results form AlchemyAPI.

Added unit test for Russian keyword extraction.
