[Mailman-i18n] sorting pygettext.py output

[Tokio Kikuchi]

Hi,

I found it a bit hard task to follow up the versions of mailman-i18n 
because pygettext.py output is random order.
Following patch and executing the script with `--style sort' option 
make the output more friendly for translaters, I believe.

Cheers,

Tokio Kikuchi
