Minor styling update.
Add Post#type and Post#data, allowing custom post types.
Update AppSignal gem.
Update jBuilder gem.
Update compass-rails and related gems.
Update CoffeeScript gems.
Temporarily disable Turbolinks until we figure out why it's breaking Chrome's form handling. :(
Re-enable Turbolinks with workaround for Chrome bug.

See https://code.google.com/p/chromium/issues/detail?id=388664 for discussion.
Also accept post[type] and post[body_html] in posts#create.
Prevent Post#type from being changed.
Add Post.blogged scope.

The idea of this scope is to include all posts that should be rendered in the user's public blog and its corresponding ATOM feed. This is mostly in preparation for the multitude (?) of different post types we'll have in the future.
Make PostFetcher delete posts if they've gone away (4xx)
When adding or removing a post, touch its referenced post if available.
Add Ping#source_guid and Ping#target_guid
Andy is finally an admin!
Rename 'Add Friend' to 'Follow'
Don't require presence of source_guid and target_guid in Pings
Replace Post#referenced_by array with attribute sourcing references from received pings.
When polling, deal with exceptions for each individual post that is being imported.
In /posts.atom, include a link to referenced posts.
