Knock status based on individual

[cormander]

As a canvassing volunteer, I need to be able to individually mark who was home, not home, etc so that I can keep better track of who's been contacted and I can mark to come back later and who to ask for, even if I speak with someone else at that address.

This feature is done when:

• I can individually mark a person with status
• I can see last status on that person
• More statuses are available, such as; come back later, non-English speaker, deceased
• The existing mark an address as not home/etc still functions
