feat(auth) confirm password

This is something important to my clients, so I thought it would be good to add it to the generator.
Also adding the  attribute to labels w/ associated IDs on inputs so clicking labels will
do as they should - focus the input.
Changes:
adding bower dep for angular-confirm-field (https://github.com/wongatech/angular-confirm-field)
adding angular dependency 'ng.confirmField' to app/index.js
adding confirm password fields to signup pages (html & jade)
adding  attribute to labels with matching ids on their corresponding inputs
repeating previous 2 steps for settings pages (html & jade)
