[RCD] Localisation of default mailbox names

Our users seem to be rather confused by the localisation which takes place on the default mailbox names:

Drafts Sent Junk Deleted Items

Largely because they are used to the names:

postponed-msgs sent-mail spam Trash

and are puzzled that the same mailbox can show up twice in the list of mailboxes with different names.

A bit of experimentation reveals that the localisation can be disabled with two separate one line changes to program/include/rcmail.php (which could be controlled by a configuration option in config/main.inc.php).

Unfortunately it isn't quite possible to do this using the Roundcube plugin architecture. Would the roundcube devs accept a small patch which doesn't change the default behaviour?
