I got rid of two of the three EXIF reads during image load.  Tested
that the EXIF data in fact is present, that the index.xml file
contains the correct angle and times, and that there's no problem with
images that don't contain EXIF data.

I didn't expect this to make much of a difference performance-wise,
but rather to my surprise it looks like it did, to the tune of 1-2% on
the SSD, and perhaps 3-5% when I uppped the scout threads.

I also capped the progress bar update to no more than every second.  I
can load about 70 files/second (20MP JPEG) from the SSD, and maybe
15/sec from the HDD.
