Removed the Facebook Friends

Got complicated trying to populate the cells in the
ListingTableViewController with the Facebook friend relationships.
Instead, will look to implement this into the segue from the view to
the ListingDetailViewController. Potentially…
Updated the Listing Detail View with Constraints

Redid the ListingDetailViewController to utilize constraints better.
Before, used a lot of “hacky” code to resize the UILabel and
UITextView. Now, utilize things like “numOfLines” for the UILabel to be
zero (0) (to automatically adjust to the needed lines), and
“sizeToContent” for the UITextView.
Added Facebook mutual Friends to Listing Details

When viewing Listing Details, a Facebook request is sent to find the
mutual friends. The friends are sent to the ListingDetailViewController
as an NSMutableArray. This array is then run against the Parse database
to find the PFUsers.

We’ve also added a UITableView to the ListingDetailViewController at
the bottom. This table populates with the mutual friends.

If my Facebook ID matches the poster’s Facebook ID (from the
ListingTableViewController), then no array is created for the
UITableView “mutual friend’s list”.

We added a FriendsTableViewCell to hold the mutual friends’ pictures
and name… to populate the UITableView.
