Implement a way to specify the spam folder

[lord-re]

On my mail server, i don't store spams in .Junks but in .Spam , i created a symlink but it would be better to add a way to tell sisyphus where to find spams.

Will add an additional environment variable to define the path to the spam folder relative to the respective maildir path.

I think as long as the format is Maildir and not mbox, it should all be fine. But you are right, I should implement a non-default configuration option. Will definitely check it out.
