Generates duplicate Posts in Stream

[StevenJoynt]

Need to use pubDate from RSS to set the date of the Post. Then we can use that to build a database query to find out if the Post is already in the Stream.
Add a config option to update the Post or just keep the original version of the News Item. Default to update the Post.

First part of solution complete: Module now sets created_at time stamp on Post to match pubDate from RSS feed.

Now searches for old post and updates it if it exists, rather than inserting a duplicate.
