Added installation instructions.
Featured images will now 'crop' themselves with a clever CSS trick, head of page should no longer have os much extra space in the title tag, and posts with external_url attribute will show a 'Visit linked content' button on the post page.
Added a few new sidebars and fixed the link for posts with external urls (link log style).
Found and fixed one more bug where the external_url link was not showing properly.
Removed the default octopress favicon and generated a Brite custom favicon.
Added a signup form for newsletters. People who download it will need to remove that.
Updated the readme
Added styling for the sidebar book signup form.
