Add extra licensing, minutes & support -> docs redirects

[hflynn]

When testing the redirect for https://trello.com/c/riJnvMrD/147-downloads-page-cc-license-link I noticed the link behind the "GNU General public license" text was a different construction and only redirecting to the top level About page so this adds that as a redirect to the licensing page too.

I realize I could also redirect more of the minutes/meetings/ URLs now the older user meetings are live but I'll do that on a follow up PR along with the other items we've identified rather than add even more here.

Deployed on ome-www-dev. The licensing and minutes redirect seems to work but not the support redirects. I will take a look at it tomorrow.

Having reviewed the different combinations, the matrix belows gives a summary of the redirects state for the site/support/bio-formats URLs

Source	Target	Status
http://ome-www-dev.openmicroscopy.org/site/support/bio-formats/	http://ome-www-dev.openmicroscopy.org/404.html	fail
http://ome-www-dev.openmicroscopy.org/site/support/bio-formats	http://ome-www-dev.openmicroscopy.org/404.html	fail
http://ome-www-dev.openmicroscopy.org/site/support/bio-formats/users	https://docs.openmicroscopy.org/latest/bio-formats/users/	pass
http://ome-www-dev.openmicroscopy.org/site/support/bio-formats/users/	https://docs.openmicroscopy.org/latest/bio-formats/users/	pass
http://ome-www-dev.openmicroscopy.org/site/support/bio-formats/index.html	https://docs.openmicroscopy.org/latest/bio-formats/index.html/	fail

I think the following redirect structure should address all cases

    - match: " ~/site/support/bio-formats(?<link>/.*)?$"
      dest: https://docs.openmicroscopy.org/latest/bio-formats$link

Sorry @sbesson I don't know why this is failing travis - the error message is about nginx and doesn't look related to my changes

[sbesson]

Sorry the trailing ; (copied pasted from #56 (review)) needs to be removed as it prevents nginx from starting

[hflynn]

Ah, I thought they were a bit random, should have checked with you!

[hflynn]

@sbesson passing travis now at least!
