Title: Fixes to handle existence of default stream_context context

In my case, the web server runs can access web data through a proxy. So I have
to define a default proxy setting for file_get_context to use by stream_context_set_deafult
function. So while a file_get_context requires to provide custom context it should
do that by changing the default context.

Also, Google OAuth2 response provides email info, so that should be returned as
user_data.
