In this patch, I implemented batch downloads for object lists.  Note that it will download the objects currently selected/shown in the list based on filtering options, not everything in the entire massive list.
If the user wants the *whole* list, they should turn off the visible objects only button and the favorites only button and set the sky quality to 1.
I also enabled the wikipedia downloading info text to overwrite previously existing downloaded info text files, so now it truly is an updater.
I also improved the search results for stars and constellations.  Also, I prevented the object description from being downloaded unless a real wikipedia article about the object is found.
There were way too many false results in the object descriptions that were downloading.  Finally, I added a progress bar for the initial object load and disabled the list access until loading is done.
It is certainly possible to make that more list specific in the future, but for now, loading everything doesn’t take too long.
