googleTrends addition

Let me know if there are some changes that should be done, I am testing this my self now and it at least has run two days in a row for me.
@amayer5125 Yes that would have been a much better starting point!  I actually had the scraping logic done so I used your branch before it was accepted (and therefore didn't have the wiki module) to at least try and run my module.  Waiting for the module code to have been accepted would have probably saved me but I really wanted to switch over to this to see how well it worked.
