Added question & answer detail view [READY]

I added the second view controller that displays the answers in a new table view. One issue I'm having is that, on my new `BLCAnswerTableViewController`, the navigation bar is covering up the contents of the first cell. Additionally, both the navigation bar and first cell are being shown under the status bar. I looked around pretty extensively for a solution, but couldn't find anything really. Any suggestions for this?

Also, if I want to continue working on the project before you've had a chance to review the pull request, should I just continue working from the `detail-view` branch? or should I merge detail-view into the master, and then create a new, separate branch?
You don't have to use `== YES` for boolean values, you can just do `if (isWritingPost)`
