new version op jquery & carousel scripts & fixes on the consumer

By using more recent versions of jquery and jquery.jcarousel now most regular browsers are supported. testen on Firefox, Chrome, Safari & IE. 

The consumer script crashed every now and then, this was caused by tweets with empty values for the user and sometimes the tweet-text. those are now ignored. 
als added some logging to the commandline so that it is clear the script is capturing tweets.
