%-variables defined in main MS config are not expanded in conf.d config files

[RobinR1]

Issue summary

%-variables defined in main MS config are not expanded in conf.d config files by MailWatch functions.
MailScanner allows to use %-variables defined in main MailScanner.conf file to be used in conf.d-config files. But MailWatch requires %-variables to be defined within the same file where they are used.

Steps to reproduce

1. Make sure some %-variables are defined in MailScanner.conf
2. some of those %variables in conf.d config files
3. Run MailWatch cron job of use web interface

Expected result

No errors

Actual result

Both apache access-log and cron system logging are full of messages like this:

PHP Notice:  Undefined index: %org-name% in /opt/mailwatch/mailscanner/functions.php on line 1894

This is expected behavior the way MailWatch currently is written, but I agree it would be proper to parse the main and conf.d counterparts in their entirety and populate those values, even if they aren't in the same file.
