[sylpheed:36282] Automatic Subject definition per folder.

[John Coppens]

Hi...

I've made a small patch which adds the possibility to automatically add a Subject field to messages, which can be defined per mail folder (addition to the already present To:, Cc:, Bcc: and ReplyTo: field).

Some mailing lists which share the same address require a tag in the Subject line (such as [EE], [OT] and [PIC] in the piclist), else they are moderated (moderator is very patient though).

If anyone is interested: http://sylpheed.sraoss.jp/redmine/issues/230
