Syndication list builder added

Added a listbuilder (login required) for the RSS and Javascript syndication lists today. The builder makes it easy to customize the lists and helps the not-too-savvy users to use the syndication features as well. Plus, it decreases the odds of errors in the syndication tags.

I will add some formatting options to the Javascript syndication soon, so that users will be more happy with the layout of their lists and it will be possible to include additional information to the HTML in addition to merely the links, raw and unexplained.

Note also that you can now extract the lists for a single category from “My spurls” instead of all your spurls as it was before.
