Verified as Boolean, instead of string

[cromulus]

Right now, Verified on the Person model is a string, which makes it difficult to turn into a default scope.

Could we make this a boolean?
What are the values so that we can make a migration to update previous values tot he boolean?

I thought about boolean.
Right now we are using the text to specify how people are being verified.
"Verified by Text Message"
"Verified by Text Message Signup"
"Verified by Josh manually"

So, maybe? I was leaving it flexible to start.

Perhaps an Enum makes sense here?
http://api.rubyonrails.org/v4.1/classes/ActiveRecord/Enum.html
and

This way, scopes for verified vs unverified could be quite easily implemented.
