[Evolution-hackers] Mailing list Actions Bounty

Hi, 

I appointed me to try this bounty so I did it, even Jorge has
delivered a patch, I had it too advanced to letting in my own computer
only, maybe this could help too.

This patch fill the requirement in this statements:

Gives Options for:
- Unsubscribe
- Subscribe
- Help
- Archives
It consider that maybe could be many url into each header so try for
the first to the last (left to right order), and even
that a header could not exist in the mail, so it don't show the
option.

This options are displayed in:

A sub-menu on Actions menu, and in the popup of mail list.
I could not do it to link on the Preview Message. Just I can't figure
how to send parameter to To: <mailto:here> so it could change the list
of options that will show in the popup menu.

The uri management code isn't the best, but I can change it.

Best regards.
