Release for 1.40 chrome app and online app

This is the first version that hte chrome app and online app are the same. 


Whats new:
* by default the app is online, reducing the number of merge conflicts in a mulit-user corpus
* by default the app uses backbone couchdb addaptor (it is a BackboneCouchDBApp) even when in a chrome extension
* a new script which finds all the user's pouches and backs them up fo the user. No more confusions about why they cant see their data on another device if they never clicked the sync button. There is no more sync button... instead we will add a user preference to go on and offline... and some logic to handle this gracefully

What is left to be done:
* gracefull online and offline with pouch
* deploy to android market/google play
