mephisto post pinger update

I’ve added support for section and tag based filtering to the post pinger. This was inspired/prompted by hank’s work adding tag based filtering to limit his postings to ruby based sites. I thought it was a great idea so it’s now in the plugin trunk. The plugin works vs the mephisto trunk as of today, no guarantees about tomorrow though.

The post pinger is a mephisto plugin that will send xmlrpc/rest pings to aggregation/notification sites when you create an article. Slightly more info is available here. As per usual you can get the plugin from: svn://hasno.info/mephisto/plugins/mephisto_post_ping.
