Twitter Updating

Revised version of the code I originally wrote about here. The main difference is that I've included a counter so it doesn't post more than two tweets every time it is run (and since it only runs once an hour, this shouldn't make it too antisocial even when it hasn't run for a while and there are a lot of items in the RSS feed).
