Add validation and correction suggestions to email address when signing in, signing up, or resetting password.
Upgrade rails
remove trailing whitespace
Refactor email validation/suggestor into an email_helper component. Update myfr so that it is used via shared code with fr2. Trigger validator/suggestion via a timeout on inputs that don't usually require a blur event before clicking submit (eg single field on form).
Update email regex to handle other allowable characters (apostrophes, dashes, and pluses).
Fix resend confirmation instructions so that a confirmation token is generated if there isn't one already. Update the missing token (confirmation error) to be formatted and have a better error message.
