Mailing list mode now includes the 'no echo' option: to only receive emails of posts not created
by you. If you reply to an email thread in mailing list mode, your reply will not then be echoed
back to you in a duplicate email by the system.
This reduces the number of scans that the db has to do in the query
to fetch orphan uploads. Futheremore, we were not batching our
records which bloats memory.

As it stands we load up user records quite frequently on the topic pages,
this in turn pulls all the columns for the users being selected, just to
discard them after they are loaded
New structure keeps all options in a discrete table, this is better organised
and allows us to easily add more column without worrying about bloating the
user table
There were actually 2 bugs:
1/ Calling '.try(:key)' on a hash doesn't work. So EmailLogs were never associated to a user.
2/ Turns out that we update the 'user.last_emailed_at' whenever we create an EmailLog (in the 'after_create' callback).
So we need to always create an EmailLog (whenever the email is sent or skipped).
