Updatng roundcube caused password and encryption errors

[Raphael Mankin]

I recently upgraded roundcube following the usual automated prompts from the software updater. This causes two problems:

1. The DB access was now set to 'no password' causing all db connections to fail. I had to edit /etc/roundcube/debian-db.php by hand to get connections to work. Editing /etc/dbconfig-common/roundcube.conf and then running dpkg-reconfigure did not work.

2. The phph mcrypt module was not properly enabled. I had to run 'php5enmod mcrypt' by hand to get things working again.
