Simplify rule inheritance control of simplified profiles

We may hide the ignore all rules / ignore one rule complexity since there may be
only one inherited rule.

Do several tweaks to make it nice.

Note it doesn't work yet until the parent rule entity isn't created, because we
are not able to detect the parent transfer...
