Add typing verification through multiple matching entries

Setting verify_match on a question will allow for
"please type it in again for verification" style entries,
such as commonly seen when setting/changing passwords, etc.

This leverages the existing gather mechanism to control asking
for multiple entries, but returns a single answer once all
gathered entries match.
