Small WSS RSS Update

I’ve made a private update to WSS RSS. The new build supports both dc:date and pubDate. Sorry Don, not enough news aggregators grok dc:date yet. Also, the new version filters expired items from the RSS feed. I’m not releasing this build – I don’t think 5 lines of code qualifies as a point release. If you want it, email me. Otherwise, I’m working on have UI support in v0.4.
