email: Improve user identification from headers

Reviewed-By: Peter Rotich <peter@osticket.com>

This is the correct logic - we'll address issue #1259 separately

Reviewed-By: Peter Rotich <peter@osticket.com>

Previously, the code would scan the email headers until it found a positive
match from any of the email headers scanned. Additionally, it would attempt
to find the user from the tagged email references header. However, this
algorithm assumed that the references header was constant and predictable in
its ordering. Recent tests with Gmail prove otherwise in some tests.

This patch changes the system so that only the tagged reference header is
included in the References header, and it will scan all items in a header
(namely the References header) until both the thread and a user are
identified. If a user can be identified, the thread and user are returned.
Otherwise, the first thread hit is returned.

email: Add MAIL_EOL setting to ost-config.php file

Reviewed-By: Peter Rotich <peter@osticket.com>

This setting allows administrators to add (uncomment) a MAIL_EOL setting in
the ost-config.php config file to define the line ending used for mail
headers and encoded bodies in outbound mail (SMTP, for instance).

By default, CRLF is used by the SMTP email generator as per the RFC 822
standard. However, many administrators can benefit by setting LF (\n) as the
line ending.

Make sure ticket create date is used on export

On some setups, IE v10 on Windows 7 at least, text added to the Redactor
editor after an image is inserted (via the image popup dialog for instance),
will not be retrieved via the ::get() method and so will not be submitted
with the form submit button.

This patch introduces a workaround by manually calling ::sync() for the
Redactor when the submit button is pressed — just before the form is
submitted.

Turns out the canned response selections for the original message and the
last message were swapped.

Previously, if the quoted response mechanism was disabled, then outgoing
mail would also not include the message-id token. This breaks the
correlation of email to ticket-thread. Now, the message-id token is always
embedded in HTML emails even if the quoted-response removal system is
disabled.

(Turns out that the message-id token was always included in text bodies.)

Previously, if the enduser registration mode were set to something other
than `public`, the agent sign-in link would not be shown. Now, the agent
sign-in link is always shown on the enduser sign-in page.

Thanks for the hint Peter.
Changed it (again) and also tested at our system. /scp/slas.php works as intended - so only the slash "/" before "scp/slas.php" was missing.

Hey again,

just found some other wrong links while I was creating a new ticket filter.

Hi guys,

here is a catch from the forum: http://osticket.com/forum/discussion/78661/invalid-sla-link-on-popup-help-tips

Since scp/ seems automatically added before slas.php just changed
scp/slas.php to slas.php

Quickly tested it and link works correctly after that little change.
