Major bugfix: Original free fiction feed

I wasn't limiting the size of feed, & was directly using all relevant content watched sources provided. And hit 512K feed size limit of feedburner sometime yesterday or today. Subscribers of both this feed & Bot SF Master feed might have noticed error getting the feed yesterday &/or today. It happened sometime between the time I checked it yesterday morning, & then today evening.

It's fixed now. I now limit the content collected to that published during the last 3 days.
