Changes requestd via PR
1) mod changed to MOD
2) autogroup changed to autogrouper
3) prints "please select at least 2 images" if user attempts to run with fewer than 2 images selected
4) change visible module name to "auto group" (lower case)
5) changed soft max on slider to 60s
- I also increase the hard max up to a full day, I saw no reason not to
