Enable disablesafemode by default.

Safemode is almost useless as is-- it only triggers in limited
 cases most of which aren't even concerning. There have been
 several proposals to remove it. But as a simpler, safer, and
 more flexible first case, simply deactivate it by default.

Anyone who wants it can re-enable and know what they've signed up for.
