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?
I see what you're trying to do here, however, it's unnecessary. It's super common for table views to have to respond to the selection of their cells that they implement a method for this already:
```objective-c
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
```
You should always use this to determine what to do when a user taps a cell. You can do away with this protocol altogether.
