Make it clearer that users can create custom relationship roles

There could be lots of room for workflow improvement under the households umbrella: when adding someone to a household, make the other people already in "relationship" to the head of household selectable. When correcting/updating an address for someone, have a pop up that allows the update to all the members of the household (or even better - check boxes for those who we might want to select). And what about an "add to household" option when on the "merge duplicates" page?

Make relationship roles dynamic. Ex. when I enter sibling for the main constituent, the drop down auto populates to sibling for the other person I am creating the relationship for
