Added browser.cookies.all() method to return all cookies. Removed ChromeCookieManager as this does not appear to be an issue any longer.

This commit also addresses issues with Chrome resolving 'localhost' to 127.0.0.1 when setting/getting cookie data. This obviously causes problems when trying to test so the fake app now uses 127.0.0.1 explicitly instead of localhost.
