[Ambassadors] Events calendars

[Paul W. Frields]

We have a wiki page for other events calendars:
  https://fedoraproject.org/wiki/Linux_Events

I added http://fossevents.org/ to that page.  But the page could use
some Ambassador's attention, and this would be a good task for a newer
Ambassador who's looking for a way to help.

It would take maybe a half-hour or so for someone to go through all
the links on that page and do some upkeep:

* See if links work, fix or remove as necessary

* If some of these sites are read-only calendars, break the page up to
  separate out and highlight sites where Ambassadors can add event
  information for Fedora events
