Comment 21 for bug 1170795

I've refactored this patch and added a release note. I can put together a live test if we think that's necessary, but the only database change is an insert for a setting, so that's unlikely to be a useful thing to test.

Here's the branch: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jboyer/lp1170795_void_deposit_on_checkin / working/user/jboyer/lp1170795_void_deposit_on_checkin
