Subject: [PATCH] loop screenshots in the mod details screen

Loop the screenshots so that clicking Next on the last screenshot will loop around to the first, and clicking Previous on the first screenshot will loop around to the last.

If there is a better way to do this, I'm happy to use it.  Brief searching was not conclusive.
