1) In DetailViewController, there’s no need to reload the project / url source list after completing a fetch
2)  Add some categories that I’ve used in the Mac version
3) Add a createdAt date to Urls.  This will require a new database.
4) Create a URLCell.  This cell allows reachability to be shown in cell for the specified URL.  The cell also keeps a reference around to the cell’s URL object.
5) In UrlListViewController, show the URLs by their createdAt Date
6) Keep track of the cells in UrlListViewController, just like we do in the Mac version, so that reachability can be maintained
7) New feature - Show a host’s favicon if it’s available in the UrlCell.
	- This downloads the favicon through a proxy, fvicon, seems to be more reliable that then google S2 thing.  It then saves the NSData to the documents folder so that it can be used again without hitting the network.
	- Not perfect.  Needs work.
8) Add to Urls object siteStatus, createdAt, and favIcon.  favIcon is the path to the data that has been saved in the app’s documents folder.
