[REMOVED] mmcFE Theme dropped from project

This fixes #874 once merged.

It will require a couple of tests by other users to ensure that
MPOS is not affected (via hard-linked URLs for example).
[UPDATE] Adding txid to base structure
[FIX] Undefined index in Mail Class
[SECURITY] Clear cache before sending a mail

Will fix an issue with users receiving wrong mails, e.g. during password
resets ONLY IF smarty cache is enabled.

Please update ASAP if you have smarty caches enabled! This is a very big
issue. By default smarty caches are disabled and not recommended to be
used. See configuration file.

Fixes #899 once merged.
