(#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.
(#2289) - document "uptodate" event

Based on discussion in #2285, it seems
we mis-documented this as the 'complete'
event, which actually never fires.
(#2281) - test against pouchdb-server
(#2143) - Make npm run build work on Windows

Just add 'node' to version and npm run build will work on Linux/OS X and Windows. Although I only tested it on Linux and Windows.
(#2143) - use fs to write a file, prepend js scripts with node, and fix jshint
(#2214) - upgrade browserify and mkdirp
