Migrate co-op pages from old site

I ran `ruby migrate_coop_pages.rb` in `scripts`. There will need to be
some manual tidying up of the generated `.md` files under `_coops` but
I think this is a good start. As a one-off it doesn't warrant the time
it would take to improve the migration script.

+We are a group of independent developers, specialized in Open Source platforms as Magento, Joomla and WordPress working from our studio in London.
+Our projects are united by a common underlying idea. Everything we do aims to empower people and go along them in the path to realize their projects.
+Part of the income from our agency work goes to create links with the community and develop social projects. So far we have engaged with projects in South America, and more recently European and UK-based projects. This is our philosophy.
