[RCD] Patch: one fix and one feature

Hi guys,

We are using roundcube at works and we found two problem we'd really like to see fixed.

The first one is trival: on/off french translation in sieve plugin are wrong telling filter is off when it's on and vice et versa.

The second is a bit more tricky: the dovecot sieve vacation feature will act only the receive mail is addressed to exactly the user's mail. But the mail I use is not LOGIN@domain but first.lastname@domain making sieve never replying. The workaround is to add my address when enabling sieve filter.

The patch I did will find my addresses from my roundcube identities and add them automatically. So our users has less things to do to make it works.

I hope you'll find them usefull.

Regards
