(#2251) - fix race condition in ldb changes
(#2158) - bring back custom extend
(#2275) - Fix ribbon overflow
(#2190) - new page about adapters

This adds a page that explains all about
the various backends and how you can use
them in different environments.

(#2281) - test against pouchdb-server
(#2143) - Make npm run build work on Windows
