[Users] Please change the tag used in mailing list subjects

This is the "Claws-mail users mailing list". If you tag all messages sent to it as just "[Users]", makes a real mess in a mail box containing messages from several other things - including users lists from other projects! Claws-mail users list is not the only one i participate, and this is probable what happens with everyone else.

So, why not use a reasonable tag like "[claws-mail users]" or, if you do not want a long one like this, just "[claws-mail]" is enough, since other lists may have less intuitive and more "acronymical" names like "[cm-dev]".
