MAID-536 Add a link to the website of SAFE Pod Montreal

I just wanted to add a link to the website of SAFE Pod Montreal.

For San Francisco, you could add a link to: http://www.meetup.com/Project-SAFE-San-Francisco/

Also, we should remove Boston for the moment. I think it was added because of http://www.meetup.com/Boston-Decentralized-Autonomous-Organization/ (it contains MaidSafe as a tag), but they haven't done any meetups about MaidSafe yet and they are not active on maidsafe.org.

On the other hand, the Sydney meetup group is making good progress (http://www.meetup.com/Sydney-Project-SAFE/). And I just noticed the [Stockholm meetup group](www.meetup.com/Stockholm-Massive-Array-of-Internet-Discussions-Meetup/) that is beginning to form.

Are you aware of other meetup groups that are being active?
