correct RSS format

John, I've identified the problem: there was no closing "description" tag, and therefore my parser could not identify the RSS contents.
So I fixed this and after checking an RSS parser (W3C) I made some minor changes to have a more consistent format for the RSS feed. I also removed the word in English ("was changed") so that we don't force a single language. Of course in the future we can have this wording in multilanguage format with the folder locales for the plugin, but I thought that simply having the name of the pad could be enough.
Please let me know if you see some bigger problem.
Greetings, 
daniel
