Extract the table view in Blog Details to Swift

[crazytonyli]

Description

This PR extracts the table view parts of the BlogDetailsViewController (in Objective-C) to a Swift implementation.

The majority of the changes are translated, without much of the swiftification. I made small improvements here and there, but not a lot.

I tried to group relevant changes into individual commits, but that turned out to be very difficult.

The BlogDetailsViewController is now pretty small. The next step is turning the view controller to Swift.

Testing instructions

The best way to test this change is to run the trunk branch and this branch on the iPad and iPhone simulators. Go to a WP.com site and a self-hosted site. You should not notice any difference in the blog details, which can be

• the left part of the split screen on the home screen on an iPad.
• WP.com site -> My Sites -> More
• The home screen of self-hosted sites.
