Title: Add a password_scheme field in mailbox table.

Add a password_scheme field in mailbox table.

This is useful if you want to deal with multiple password scheme. The
one you use today might be too weak in the future and you should have
the possibility to change it.

The password scheme names stored in this new field are the one
described here : http://wiki2.dovecot.org/Authentication/PasswordSchemes

To use it with Dovecot, you just have to do a query like :
```
SELECT CONCAT('{', password_scheme, '}', password) FROM `mailbox`
WHERE [...]
```

The password_scheme field will contain an empty string for password
which have been set before this change.
