Add suggested Custom Rules to footprints
Description
Footprints lacks proper documentation fields, at least field for copyright notice has been reported elsewhere. It could be useful to have a place for suggested Custom Rules. Some footprint would benefit from rules written especially for them, but now the rules have to be managed completely separately. If there would be a text property for suggested rules, the rules editor error check could see if there are rules in footprints and give a notice if they are not used.
Applying rules automatically is an enticing idea, but it probably wouldn't work flexibly and safely enough.
I happen to have only v6.0 here, but this is relevant for 6.99, too.
