[Dovecot] New script mdsmon

[Antonio Casado Rodríguez]

Hi all,

I have created mdsmon (MailDirSize Monitor) script modifying postmmon 
(POSTfix Mbox Monitor) script of Ricardo Malafaia.

Features:
- It works with maildirsize file of users. (all inbox folders in one 
directory).
- It sends alert and warning mails to users if quota is above 50% or 85%.
- It creates accounting file.


All the suggestions and errors are welcome:
