[imp] Always show same email header field in mailbox listing

[Arminas]

Hi,

the list of messages in mailbox view in IMP contains some fields-columns
with automatically generated values. e.g. "From" column - if message was
sent by currently logged in user, "To:" information is used instead of
"From:".

IMHO it would be useful to have ability to disable this feature in IMP's
configuration.

However, I would like to disable it now. Where should I alter the code?
Maybe in imp/lib/Ui/Mailbox.php getFrom() function? Is this function also
used to get "To" field value, while listing sent mail mailboxes?
