Fixing Google and other bots

I'm including new code in the session handler to NOT propegate the session id in the URL when a bot comes to spider the site. This will cut down on the search engine traffic dramatically.

I would atleast leave the ability for the google spider to provide ref. Relying on word of mouth alone may not be the only audience your looking for.

All bots are still allowed to spider, I just took away the random generating session ids in the url. Everytime a bot would come to the site, it would see 'new' pages to crawl.
