Verification of phone number

[natea]

Provide a user interface for the user to verify their phone number with Twilio. I think there is already code in views.py to do the actual verification, but we need to expose a UI for the user to do this one-time process, preferably at the same time that they are signing up for an account.

A user's phone number is automatically and transparently verified when they sign up for an account. Currently there is no mechanism for an existing user to verify a new number or try a re-verification on their current number. Do we want to provide this functionality?

Yes, I think if the verification fails for some reason, we need to provide a facility whereby they can try the verification again. Or if they change their phone number to something other than the one that they used when they registered, then we need to re-verify it.
