Create <SecureSubmit /> Component

[jbaxleyiii]

The <SecureSubmit /> component should be used in forms where sensitive data is being submitted or updated. It should check the session duration of the logged in user, and if it is over a certain amount of time, open a modal to require password and explain why.

<SecureSubmit
  onSubmit=Function
  sessionMax=Number
  message=String
  validationForm=Component // defaults to password re-entry
/>

This component (and corresponding form component) could be hooked into various security systems (touch id, android touch, phone number, questions, password, etc).
