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.

Also, allow for the administrator to manually define the ROOT_PATH in the
config file (the very last mile).

Historically, ROOT_PATH and ROOT_DIR contained the same value; however,
ROOT_PATH now points to the URL path where osTicket is installed, whereas
ROOT_DIR points to the file system location where osTicket is installed.
