Bountiful Temple Rework

I noticed a few things on the original print file that were a little funky when I went to print it, there were 10 shells instead of a single watertight model and not all parts of the model would print the way I imagine was intended (image shows the watertight model on the left, original on the right).

I modified the model to be a single watertight shell, fixed/tweaked a few other minor errors in the file itself, then modified the big windows on the sides to be a bit more print-friendly and tweaked the windows on the steeple to print a little better as well.

The original file would probably print just fine, but this one should print a little better.
