Scroll to selected blog after adding it

[isaackeyet]

Minor issue, but if you have many blogs in the app and add a new one, finding it on the list can be tough at first.
We should:
Scroll to the newly added blog
Probably show it (push the blog view controller)
Probably do nothing if more than one was added.
