JIRA internal support requests are not being assigned the Reporter who is the contact for the Support Request

When a JIRA instance is used to create a Support Request from the Support Request page, and the resulting email is processed by the CreateSupportRequestHandler at https://support.atlassian.com the reporter is set to the user from the email's FROM address. This is set for the SMTP server properties, and is not the email address sent in the body of the email as the Contact for the support request.

There are two things that need to be fixed:
1. Fix the CreateSupportRequestHandler to look for a user based on the REPLY-TO header, OR the Contact Info portion of the email OR the TO header (in that order)
2. Fix the JIRA Support Request to use the Contact Info section to set the REPLY-TO header in the sent support request email.

The combination of these two will preserve backward compatibility for old versions of JIRA.

Please see this issue for confirmation of the behaviour.
