Blog It Link with Stories

This is a simple patch which does the following:
1. Adds the "blog it" link functionality to the story module.
2. Adds "blog it" links to the news aggregator summary pages rather than just the blocks.
3. Utilizes the quote module, if available, when inserting the text from the feed item to the story or blog entry.

This is useful because many are using the story module instead of the blog module to maintain one personal blog on their drupal site. If both the story and blog module are activated, the "blog it" link defaults to creating a blog entry.

Changes have been made to the files story.module, blog.module, aggregator.module, and drupal.css.
