Title: Show reply-to if it exists

If there is a reply-to address, show it also.

Based on the type of email being sent by the app, it is common for us to have the reply-to address be different from the from address. It is useful to see this when letter_opener renders the email.

This is similar to a set of commits I contributed to the 37signals mail_view gem.
