Add an attachment when sending email

Hi,

There is some code sending emails with attachments : it is for automatic import, attaching import log file.

The limitations are
1) the email function must be the anonymous one (using smtp serveur without user/pwd), not the ssl one.
2) the attached files are pure text files.

Code is in /model/Cron.php, line 402 and after.
Mail function is standard one, in sendMailAnonymous() in /tool/projector.php
