fix email logic and add nonoko setting to selectbox

Changes it so that if the user is mod and they can bypass fields, "email" will show up just fine. If not, "email" will become an options field, like on 4chan. The options field will show up for anybody if hide_email is set to true.
Nonoko will be in the selectbox if always_noko is set to true.
