#2705 - Allow emails to support ticket email integration from emails not associated with a member

It's more complex than this. I started making quick changes then realised...

Complexities:
1) A big part of this is permissions. We need to check the user has access to reply to an existing ticket, because allowing third parties in looks like a scary security hole to anyone using tickets.
2) We need to include the email address of the user in the ticket like we do for normal guest tickets. That would therefore require further changes.

Re-creating more clearly.
