BackupPC_sendEmail is missing a "use" directive to support encode.

The perl script that sends email notification is missing a "use" directive to support mail encoding.
Here are the steps to reproduce the bug :

su backuppc
$ /usr/share/backuppc/bin/BackupPC_sendEmail -u [removed for privacy]
Sending test email using /usr/sbin/sendmail -t -f backuppc01.norris
Undefined subroutine &main::encode called at /usr/share/backuppc/bin/BackupPC_sendEmail line 405.
sendmail: No recipients specified although -t option used

The bug is fixed upstream in BackupPC version 3.2.0 but this version is tagged as beta quality. Currently, Intrepid, Jaunty and Karmic all use BackupPC version 3.1.0 and are affected by this bug. I would suggest to just fix this issue and keep the stable release. The fix is a one liner and should cause no problem :
