localStorage issue in Chrome extension

Chrome extension does not support window.localStorage, and If you try to use the library to build an extension for Chrome you run into error `window.localStorage is not available in packaged apps. Use chrome.storage.local instead.` Quick fix for that is basically assign chrome.storage.local to
window.localStorage `window.localStorage = chrome.storage.local;` before create client, also to make it work you need to add `storage` permission to a manifest file.
