Create insecure-guest group by default

New insecure guest group is based on #2065 and includes vanilla-like permissions.

This discussion item includes tshock.ignore.*, which this change does not include. Attempting to strike a balance between reason and usefulness, most changes are applied for vanilla use, but not hacked client use.
