This patch addresses several key issues with whats interesting.  First, on Macs it will first check inside the app bundle for the whats interesting before it checks in the data directory.  That way if the user installed from a dmg and then updated to a new dmg the any whats interesting improvements will be included.  It still checks the data directory as a backup in case the user didn’t install from a dmg. Second, when there are no objects in a list, it displays a nice message explaining that, rather than just a blank screen.  Also I added Supernovas, the NGC Catalog, the IC Catalog, and the Sharpless Catalog.  I also added some more objects to the object lists.  For the catalogs, I made them load separately on demand with a nice progress bar and a message explaining that they are loading.  Also I corrected a bug for the moon and similar objects that were not object types originally included in Whats Interesting.  I also disabled automatic downloading for object information because I don’t think it should be initiating lots of network traffic when there is no internet connection and also it shouldn’t try to download data many many times for objects that really have no article.  The user can now initiate the download of all the data for the entire list, for individual objects, or just objects that have no data, so that should be fine.  I also did a little rearranging on the category screen.  Also just in case, I added some checks to see if some objects are null for safety.
