Put info on Safe Mode back into the Help Files

Not precisely a feature request, but this doesn't fit clearly in any of the topic categories.

I discovered today that the help files no longer include information on how to Access Accordance's Safe Mode--or at least I can't find it by searching for Safe Mode, and it is not listed in the S section of the alphabetical listing.

There are references to Safe Mode in several places (including some of the “New in Accordance x” sections, but none of them link to a discussion of how to turn on see mode.
